Question

Two cars are travelling side by side down a straight road in opposite directions.Both cars are travelling at a speed of 22m/s. What is their relative speed ?

Answer 1

Answer:

Their relative speed is 44 m/s

Explanation:

* Lets explain what is the relative speed

Relative motion is the change in position with time of one object

compared to another object.

If objects moving in the same direction towards, or away from, each

other, then relative speed is ⇒ fastest speed – slowest speed

If objects moving in opposite directions towards, or away from, each

other, then relative speed is ⇒ the sum of the two speeds together

* Lets solve the problem

Two cars are travelling side by side down a straight road in opposite

directions.

Both cars are travelling at a speed of 22 m/s

The two cars are travelling in opposite direction, then the relative

speed is the sum of their speed together

They are travelling at the same speed 22 m/s.

Then their relative speed = 22 + 22= 44 m/s

* Their relative speed is 44 m/s
