Expert Answer

During first 2hr 10 min :

speed = distance / time

here distance = 500m

time = 2hr 10 min = 130 min = 780 sec.

so , speed = 500m / 780sec

                   = 0.64m/s

Also average velocity = 0.64 m/s.

We cannot entertain multiple question of this type, please post each question individually .
