Question

Two cars travel along a highway at the same speed.

Car A travels 20 km in 12 min.
How long will it take Car B to travel 50 km?

Answer 1

30 mins

Explanation:

speed = distance/ time

speed of car A

= 20/ 12 km/ min

= 5/ 3 km/ min

also, speed of car A = speed of car B

speed of car B = 5/ 3 km/ min = 50km / time taken (in mins)

`(5)/(3) = (50)/(t)`

`5t = 150`

`t = 30`

=> t = 30 mins
