Question

If a sound travels a distance of 100 m in 2 s, its velocity is ____ m/s.

  1. 100
  2. 50
  3. 180
  4. 200

hintHint:

Distance= speed × time.

The correct answer is: 50


    • Formula: Distance= speed × time.
    • Given that, distance= 100m and time= 2s.
    • Therefore, 100= speed × 2.
    • Speed = 100/2
    • Therefore, speed= 50m/s.
    • So, the correct option is b.
