Question

5) Rakesh went from Delhi to Agra on his motorbike. The odometer of the bike reads 4200km at the start of the trip and 4460km at the end of his trip. If Rakesh took 4h 20min to complete his trip, find the average speed in km/h as well as m/s.

Answer 1

From the reading on the odometer, we can get the distance Travelled.

We do this by :

Subtracting the initial reading from the final reading.

Distance = 260Km

The time taken is :

4 h 20 minutes.

We convert this to hours.

13 /3 hrs

Speed = Distance ÷ time

260 × 3 /13 = 60 Km/h

In m/s:

5 / 18 × 60 = 16.67 m/s
