Question

A car travels first 60 km in 2 hours and next 100 km in 3 hours. Find the average speed of the car.
$\left[2Marks\right]$

Answer 1

Average speed = $\frac{\text{Total Distance travelled}}{\text{Total time taken}}$

Here, total distance travelled = 60 km + 100 km

= 160 km
$\left[1Mark\right]$

and, total time = 2 hours + 3 hours

= 5 hours

$\therefore$ Average speed = $\frac{160}{5}$

= 32 $km{h}^{-1}$
$\left[1Mark\right]$
