271. A school day starts at 8:50 with a ten-minute registration period. Before lunch, there are three lessons which are each fifty-five minutes and one fifteen-minute break. Lunch is one hour. What time does lunch finish?

Check answer and explanation

Answer: (Give your answer using the 24-hour clock.)

Explanation - Start time: 08:50 - Registration: 10 minutes → 08:50 + 10 min = 09:00 - 3 lessons × 55 minutes = 165 minutes → 09:00 + 165 min = 11:45 - Break: 15 minutes → 11:45 + 15 min = 12:00 - Lunch: 1 hour → 12:00 + 1 hour = 13:00

272. Train speed is double of car. Car covers 60 km in 1 hour. Distance by train in 30 minutes?

Check answer and explanation

Answer: 60 km

Explanation Given: The car covers 60 km in 1 hour Train speed = twice the speed of the car Time = 30 minutes (½ hour) Step 1: Find train speed Car speed = 60 km/h Train speed = 2 × 60 = 120 km/h Step 2: Distance formula Distance = Speed × Time Time = 30 minutes = 0.5 hour Distance by train = 120 × 0.5 = 60 km

273. Find the time when the Simple Interest is 81, Principal is 450, and Rate is 5%.

Check answer and explanation

Answer: 3.6 years

Explanation Given: SI (Simple Interest) = 81 P (Principal) = 450 R (Rate) = 5% Time (T) = ? Using the formula: SI = frac{P times R times T}{100} S I = P × R × T/100 ​ Substituting the values: 81 = frac{450 times 5 times T}{100} 81 = 450 × 5 × T/100 ​ 81 = frac{2250 times T}{100} 81 = 2250 × T/100 ​ 81 = 22.5 times T 81 = 22.5 × T T = frac{81}{22.5} T =81/ 22.5 ​ T = 3.6 text{years} T = 3.6 years

The carpenter cannot work on Monday or Tuesday Question : In Case the painter works on Thursday, which among the following alternatives is possible A. The election works on Tuesday B. the election works on Friday C. the interior decorator does his work after the pinter D. plumber and the painter work on consecutive days E. Mrs. Kamran Cannat Fit All of the Workers into the Schedule

275. If 10 men can construct a 75 km long road in 5 days. How many days will be needed for 15 men to construct a 45 km long road?

Check answer and explanation

Answer: 2 days

Explanation First, let's find the work rate of 10 men: 10 men construct 75 km in 5 days, so: Work rate = 75 km / 5 days = 15 km/day for 10 men Now, let's find the work rate for 15 men: Work rate for 15 men = (15/10) × 15 km/day = 22.5 km/day Now, let's find the time needed for 15 men to construct 45 km: Time = Distance / Work rate = 45 km / 22.5 km/day = 2 days

276. Hyder Ali 600 km to his home partly by train and partly by car. He takes 8 hours if he travels 120 km by train and the rest by car. He takes 20 minutes longer if he travels 200 km by train and the rest by car. Find the speed of the train and the car.

Check answer and explanation

Answer: Speed of the train = 60 km/h, Speed of the car = 80 km/h.

Explanation Let the speed of the train be x km/h and the speed of the car be y km/h. Case 1: He travels 120 km by train and the rest (480 km) by car, taking 8 hours in total. Time taken by train = Distance / Speed = 120 km / x km/h = 120/x hours Time taken by car = Distance / Speed = 480 km / y km/h = 480/y hours Total time = 8 hours = (120/x) + (480/y) Case 2: He travels 200 km by train and the rest (400 km) by car, taking 8 hours 20 minutes (or 8.33 hours) in total. Time taken by train = Distance / Speed = 200 km / x km/h = 200/x hours Time taken by car = Distance / Speed = 400 km / y km/h = 400/y hours Total time = 8.33 hours = (200/x) + (400/y) Now, we have two equations and two variables. Solving them simultaneously, we get: x = 60 km/h (speed of the train) y = 80 km/h (speed of the car)

277. The motorbike covers 80 km in 2 hours, and its speed is?

Check answer and explanation

Answer: 40 km/h

Explanation Calculating the Speed Distance = 80 km Time = 2 hours Speed = Distance/Time} = 80/2 = 40 km/h

278. The speed of a boat in upstream is 60 kmph and the speed of the boat downstream is 80 kmph. Find the speed of the boat in still water and the speed of the stream?

Check answer and explanation

Answer: 70, 10 kmph

Explanation Given: - Upstream speed = 60 km/h - Downstream speed = 80 km/h Let: - Speed of boat in still water = x km/h - Speed of stream = y km/h Formulas: - Upstream speed = x - y = 60 - Downstream speed = x + y = 80 Add the two equations: (x - y) + (x + y) = 60 + 80 2x = 140 x = 70 km/h (speed of boat in still water) Find y: x + y = 80 70 + y = 80 y = 10 km/h (speed of stream)

279. A traveling wave on a rope has a frequency of 2.5 Hz. If the speed of the wave is 1.5 m/s, what are its period and wavelenght

Check answer and explanation

Answer: 0.4 s, 0.6 m

Explanation To find the period and wavelength of a wave, we can use the formulas : Period (T) = 1 / Frequency (f) Wavelength (λ) = Speed (v) / Frequency (f) Given : Frequency (f) = 2.5 Hz Speed (v) = 1.5 m/s Step 1: Calculate the period (T): Using the formula, T = 1 / f, we can substitute the given frequency to find the period: T = 1 / 2.5 Hz T = 0.4 s Therefore, the period of the wave is 0.4 seconds. Step 2: Calculate the wavelength (λ): Using the formula, λ = v / f, we can substitute the given speed and frequency to find the wavelength: λ = 1.5 m/s / 2.5 Hz λ = 0.6 m Therefore, the wavelength of the wave is 0.6 meters. In summary, the wave has a period of 0.4 seconds and a wavelength of 0.6 meters.

280. A motorcyclist travels 200 km in 1 hour. How many minutes it would take him to travel 120 km?

Check answer and explanation

Answer: 36 minutes

Explanation To find the time it takes to travel 120 km: Speed = Distance / Time = 200 km / 1 hour = 200 km/h Time to travel 120 km = Distance / Speed = 120 km / 200 km/h = 0.6 hours Convert hours to minutes: 0.6 hours * 60 minutes/hour = 36 minutes The correct answer is: 36 minutes
