Question

21. A body moves 600 m in a
direction in 20 sec. The velocity of
the body
10 m/s
20 m/s
30 m/s
40 m/s s​

Answer 1

Answer:

30 m/s

Explanation:

A body moves 600 m. in 20sec.

In 1 sec. the body moves (600÷20)m.

= 30m.

Answer 2

$\sf\small\blue{Given:-}$

• Time = 20 sec

• Speed = 600m

• Velocity = ?

$\sf\small\blue{Find:-}$

• Velocity of the body.

$\sf\small\blue{formula:-}$

• Average speed = Distance/ Time

$\sf\small\blue{Solution:-}$

✈︎Speed = Distance /time

✈︎600 = 20/t

✈︎T = 600 / 20

✈︎T = 30 m/sec .

$\sf\small\blue{Note:-}$

• The velocity of the body is 30 m/sec.
