Solution

The correct option is C
5 m/s

Average speed = Distance travelled / Time taken
$= \frac{36}{2} k m / h$
$= 18 k m / h$
$= 18 \times (\frac{5}{18}) m / s$
$= 5 m / s$

A car travels 36 km in 2 hours. Its average speed is:

The correct option is C 5 m/s Average speed = Distance travelled / Time taken =362 km/h =18 km/h =18×(518) m/s =5 m/s

The correct option is C
5 m/s

Average speed = Distance travelled / Time taken
$= \frac{36}{2} k m / h$
$= 18 k m / h$
$= 18 \times (\frac{5}{18}) m / s$
$= 5 m / s$
