Question

What is the average velocity if a body covers first 10 km in 2 hours and next 20 km in 3 hours?

Answer 1

Given;

distance 1 = 10km

distance 2 = 20km

time period 1 = 2 hrs

time period 2 = 3 hrs

Thus average speed = total distance / total time

• V = 10 + 20 / 2 + 3
• V = 30 / 5
• V = 6 kmph
