Question

Answer 1

Speed is the rate of change of motion

speed = distance/time

so speed of car = 160/4

=

40 km/hr

Answer 2

Answer:

Speed is the distance traveled per unit of time. It is how fast an object is moving.

To find the speed of a body, there is a formula :-

Speed ( v ) = distance (d) / time (t)

Here, d = 160km &

t = 4hours

So, speed = 160 km /4h

= 40km/h.
