ANSWER:

  1. no car is not moving with constant speed
  2. average speed = total distance covered/ total time taken

so , 15 +28 +40+ 60/ 1:30 min

average speed = 143/5400

average speed = 6.143

3. from 12:00 to 12:30 pm car travels 20 km in 30 mins

from 11:30 to 12:00 car travels only 12 km in 30 mins

and from 11:00 to 11:30 car travels only 13km

hence maximum velocity is between 12 :00 to 12:30

Explanation:

In second case

we will not consider time from 10:30 because cae has do not cover any distance in that duration.

so we will add from 11:00 to 12:30 which is

1:30 ( one hour thirty mins )
