Question
A car travels at a speed that is 30 km/h faster than a
bike's speed. The bike covers a distance of 750 km in 15 hours. Calculate the time it takes for the car to cover a distance that is 850 km greater than the bike's distance.Solution
Let's assume the speed of the bike be 'x' km/h ATQ; x = 750/15 = 50 km/hr So, speed of the car = (50 + 30) = 80 km/h Required time taken = {(750 + 850)/20} = (1600/80) = 20 hours Hence, option b.
