Question

A car covers 72 km in 2 hours and a train covers 120 km in 3 hours. Find the ratio of the speeds.

Answer 1

Answer:

9 : 10

Step-by-step explanation:

Find the speed of the car:

Speed = Distance ÷ Time

Speed = 72 ÷ 2 = 36 km/h

Find the speed of the train:

Speed = Distance ÷ Time

Speed = 120 ÷ 3 = 40 km/h

Find the ratio of the speed:

Car : Train = 36 : 40

Divide by 4 through:

Car : Train = 9 : 10

Answer: The ratio is 9 : 10
