Question

BRAINLIEST !! BRAINLIEST !!​

Answer 1

Answer:

a) From time 0 to 10 minutes.

b) From time 10 to 20 minutes.

c) Distance = area under speed-time graph

                  = 1/2 *10*40/60 (km)

                  = 0.33 km.

d) Distance = area = 0.33 km.

e) Average speed = total distance/total time

                              = $[\frac{0.33+0.33}{10+10}] *60$

                              = 1.98   kmph.
