A car is running at 72 km/h. How much distance it would cover in 10 seconds?
(A) 100 m
(B) 150 m
(C) 200 m
(D) 250 m
(E) None of the above
Speed of car is given in km/h. Let's first convert this into m/sec.
Speed of car = 72 km/h m/sec = 20 m/s
Distance = Speed x Time = 20 x 10 = 200 m
Therefore, the car at the speed of 20 m/s would cover 200 metres in 10 seconds.
Hence, the answer is (C).
