Answer:
FROM A-B
SPEED= D/T (DISTANCE/TIME)
= 3/5 CM/SEC
FROM B-C
SPEED= D/T
=3/7 D/T (BODY AT REST)
FROM C-D
SPEED= D/T
=7/9 CM/SEC

Answer:The speed of the body between A to B
Distance: 3cm = 0.03m
Time: 5-2= 3sec
Speed= d/t = 0.03/3 = 0.01m/s
The speed of the body between B to C
Distance: as the slope is parallel to x-axis the body is at rest
Time: 7-5=2sec
Speed=d/t = 0/2 = 0m/s
The speed of the body between C to D
Distance: 7-3= 4cm = 0.04m
Time: 9-7= 2sec
Speed=d/t =0.04/2 = 0.02m/s
