To cover a distance of 216 km in 3.2 hours, what should be the average speed of the car in meters/second?
The car covers 216 km in 3.2 hours
Speed of car (in km/hr) = $$\frac{216}{3.2} = 67.5$$ km/hr
=> Speed in m/s = $$67.5 \times \frac{5}{18}$$
= $$5 \times 3.75 = 18.75$$ m/s
$$\therefore$$ In 1 second, it travels 18.75 metres
