Question

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

Answer 1

Step-by-step explanation:

Given:-

• car covers 72 km in 2 hours
• train covers 120 km in 3 hours

To find:-

• ratio of their speeds.

Then Car speed :-

$⟹speed= \frac{distance}{time} \\⟹ \frac{72}{2} \\ ⟹36kmph$

Car=36km/h

Then Train Speed:-

$⟹ \frac{d}{t} \\ ⟹ \frac{120}{3} \\⟹40kmph$

Train:- 40km/h

Then ratio= Car:Train

⟹ 36 : 40

⟹ 9 : 10.. is the correct answer..
