A truck covers a distance of 640 km in 10 h. A car covers the same distance in 8 h. What is the respective ratio between the speed of the truck and the car?
We know the formula of speed which is Speed = Distance/Time
Speed of a truck = 640/10 = 64
Speed of a car = 640/8 = 80
Ratio of speed of truck and car = 64:80 = 4:5
