Question 55

A car covers a certain distance at a speed of 54 km/hr in 7 hours. What should be the speed of car to cover the same distance in 6 hours?

Given, Speed of the car = 54 km/hr
Time taken to travel the distance = 7 hours
Then, Total distance travelled by the car = 54*7 = 378 km
Required speed to travel 378 km in 6 hours = $$\dfrac{378}{6} = 63$$ km/hr
