Question

a car covers 70 kilometre in 2 hours and the train covers 120 km in 3 hours find the ratio of their speeds​

Answer 1

Answer:

Speed of Car per hour = 70 ÷ 2 = 35

speed of Train per hour = 120 ÷ 3 = 40

Average speed = 35/40 = 7/8 = 7:8

Step-by-step explanation:

First of all, You have to find out the speed of car and train, then you have to divide the speed until you get the lowest term.

Answer 2

Answer:

speed = Distance /Time

So,

a car speed (s)= 70/2=35

a train speed (s)= 120/3=40

the ratio between 35 and 40

35/40

7/8

the ratio is the 7:8
