Answer 1

1. At the time of 1st second the body covered 6 meters it stands 3seconds rest then again started moving and in the fifth second the body reaches 18 meters. So, distance covered during 1st second to the 5th second = 18-6
= 12meters.

2. Distance covered = 12 meters
Time taken = 4 seconds

Speed = Distance ÷ Time
= 12 ÷ 4
= 3 meters per second
= 3 m/s
