Question

What is the time taken for a plane travelling at 100 m/s to cover 3 km?​

Answer 1

30s

Step-by-step explanation:

time = distance/speed so,

t=3km /100m/s but both distance and speed should have the same unit so..

3km is converted to meters to get 3,000 m.

Therefore:

t= d/s

t= 3,000m/ 100m/s

t= 30s
