Question

A car travels 120km at a certain speed. If the journey takes 2 1/2{Two and the half hours}, find the average speed{Let the speed be v km/h}

Answer 1

48 km/h

Explanation:

Distance = 120 km

Time = 2½ h

Speed = ?

We know that

Speed = Distance/Speed

Let,

Speed = v km/h

=> v = 120/(2½)

=> v = 120/(5/2)

=> v = 120 × 2/5

=> v = 24 × 2

=> v = 48 km/h

Average speed is 48 km/h
