Question Calculate the speed of a car that travels 150 metres in 10 seconds. Express your answer in km/h.
Distance = 150 m
Time taken = 10 s
SPeed = \(\frac{\text { Distance covered }}{\text { Time taken }}\) = \(\frac{150 \mathrm{~m}}{10 \mathrm{~s}}\)
SPeed in km/hr = 15 × \(\frac{18}{5}\) = 54 km/h
