Answer:

D 15m/s

Explanation:

1)you find the speed covered in all the points e.g on speed=distance covered

time taken

a)300m\15s=20m/s

b)rest no distance covered

c)(1000-300)=700m time=(60-35)=25. 700m/25s=28m/s

d)(1200-1000)=300m time=(80-60)=20s

200m/20s=10m/s

thus the lowest speed was 10m/s at D

Average speed=average distance

average time

=1200m/80s. =15m/s
