Question

The odometer of a moving car reads 4820.0 km when the clock shows the time 08:30 AM. At 08:50 AM,
the odometer reading shows 4864.0km? What is the speed of the car in km/h during this time?

Answer 1

Answer:

Explanation: Readings of car at the starting = 4820

Readings of car at the end = 4864

time taken = 20 minutes = 20/60 = 1/3 hrs

Distance = 4864 - 4820

               = 44 km

speed =  distance / time

          = $\frac{44}{\frac{1}{3} }$ = 44 X $\frac{3}{1}$

                 = 44 X 3

= 132 km/hr
