Question

A vehicle covers a distance of
400km in 5 hour. Calculate its
average speed.

Answer 1

Everybody knows that Speed is the distance covered by a body in a specific unit of time.

If S = speed, d = distance, and t = time, Then S = d/t

The vehicle covers 400 km in 5 hours

Therefore the Average speed (S) = 400/5 = 80 km/hr.

The km/hr is the unit of speed here as the vehicle travelled in kilometers and the time taken is an hour for that. 

Answer 2

Answer:

vehicle covers 400 km in 5 hours.

Explanation:

therefore the average speed (S) =400/5=80km/hr.
