Question

A body covers 10m in the first 5s and 20m in the next 5s.find its average speed

Answer 1

Answer:3 m/$s^{2}$

Explanation:

Answer 2

Answer:

The average speed of the body is equal to 3ms⁻¹.

Explanation:

Consider that a body moves from point A to point b in 5s

The distance AB covered by body = 10m

Then further body moves point B to point C in 5s.

The distance BC covered by body in next 5s = 20m

The total distance covered = AB + BC = 10 + 20 = 30m

The total time taken = 5 + 5 = 10s

Average speed is calculated from the ratio of total distance covered divided by the total time taken.

Average speed = $=\frac{30m}{10s} =3m/s$

Therefore the average speed of the body is equal to 3m/s.
