Question

A truck is coming towards you from a distance
of 1000m on a straight road at time t=0. At
time t=10 seconds it is at a distance of 900 m.
The average velocity in m/sec is
A: 17
B: 12
C: 14
D: 10​

Answer 1

Answer:

D] 10 m/sec

Explanation:

At 0 second it was 1000m away and at 10 second it was 900m away.

So 1000-900=100m

To cover 100m it took 10 seconds

So to cover Xm it took 1 second

100*1/10= 10m it covered in 1 second

So the final answer is [D]: 10 metres/second
