A car (A) is moving with a speed of 40 ...

A car (A) is moving with a speed of ` 40 km h^(-1)` and car (B) is moving with a speed of 60 km h^(-1)` , along parallel straight paths, starting from the same point . What is the position of car (A) w.r.t. (B) after `15 minutes` ?

Text Solution

Verified by Experts

Rwlative velocity of car ` A w.r.t. B`, ` v_(AB) = 40 40 - 60 =- 20 km//h , Separation of car (A) from car (B) in `15 minutes =- 20 xx `15//60 =- 5 km`.
