Two cars are moving in the same direction with their respective speeds of 9 km/h and 5 km/h. Find the relative speed of 1st car with respect of 2nd.
-
- 2 km/h
- 4 km/h
- 8 km/h
- 6 km/h
Correct Option: B
We know that for relative speed, the subtraction of speeds takes place, if the motions of the two objects are in the same direction.
∴ Required relative speed = 9 - 5 = 4 km/h
