Multiple choice

A car covered a distance of 840 km in 14 hours. Ratio of the speed of bike to speed of the car is 4: 3 and the ratio of the speed of bus to bike is 1: 2. In how much distance will the bus cover in 8 hours?

  1. 240 km

  2. 320 km

  3. 400 km

  4. 160 km

B Correct answer
Explanation

Car speed = 840/14 = 60 km/hr. Bike speed = (4/3)*60 = 80 km/hr. Bus speed = (1/2)*80 = 40 km/hr. Distance covered by bus in 8 hours = 40 * 8 = 320 km.

AI explanation

Using the formula Speed equals Distance divided by Time, the speed of the car is 840 divided by 14, which is 60 kmph. Given the ratio of the speed of the bike to the car is 4 to 3, the bike's speed is 4/3 of 60, which equals 80 kmph. Given the ratio of the speed of the bus to the bike is 1 to 2, the bus speed is 40 kmph. Using the formula Distance equals Speed multiplied by Time, the bus covers 40 times 8 hours, which is 320 km.
