Question

4.

A car is moving along a straight line, say
OP. It moves from O to P in 18 s
return from Pto Q in 6 s. What are the av
age velocity and average speed of the car in
going from O to P and back to Q?

0-O
40
80
120
160
200
240-Q
280
320
360-P

(0-360) is a number line.​

Answer 1

Answer:

average velocity = displacement/ time interval

velocity= 360/18s

average speed= path length/ time interval

360m/18s=20ms
