Question

The ratio of the speed of a train and a car is 16 : 15. Also, a bus covered a distance of 480 km in 8 hours. The speed of the bus is three-fourth the speed of the train. How much distance will the car cover in 6 hours?

• A. 450 km
• B. 480 km
• C. 360 km
• D. Cannot be determined
• E. None of these

Answer 1

The correct option is A

450 km

Given that the bus covered a distance of 480 km in 8 hours.

Therefore, speed of the bus $=\frac{480}{8}=60$ km/hr

Also given that the speed of the bus is $\frac{3}{4}$ of the speed of the train.

Therefore, speed of the train = 80 km/hr

Speed of the car $=\frac{15\times 80}{16}=75$ km/hr

Now required distance = speed $\times$ time = 75 $\times$ 6 = 450 km
