Question

Two cars are initially 10 miles parat on the same straight road and are moving towards each other. One car is going 30 miles per hour and the other car is going 36 miles per hour. How far apart are the two cars 2 minutes later?

Answer 1

Let's break down the given information.

Car A

Speed - 30 mph

Hence the distance traveled per minute would 30/60 mph which is 0.5 Miles every minute.

Car B

Speed - 36 mph

The distance traveled per minute would 36/60 mph which is 0.6 Miles every minute.

Initial distance between the cars is 10 Miles

Car A travels 1 miles in 2 minutes and Car B travels 1.2 miles in 2 minutes.

Hence to calculate the distance between the 2 cars we need to calculate

Initial distance - Distance travelled by Car A - Distance traveled by Car B

Which is

10 - 1 - 1.2

7.8 Miles distance between the 2 cars
