Answer to Question #246406 in Physics for Chethana

Question

The reading on the odometer of a car at 8:40am is 55,891km. After traveling a certain distance the odometer shows 55,912km at 8:50am. Calculate the average speed of the car in km/h

Answer 1

We can find the average speed of the car as follows:

$$v_{avg}=\dfrac{\Delta s}{\Delta t},$$ $$v_{avg}=\dfrac{55912\ km-55891\ km}{10\ min\cdot\dfrac{1\ h}{60\ min}}=126\ \dfrac{km}{h}.$$
