Speed of a man is 45 km/h. In how much time (in seconds) will he cover a distance of 225 metres?
Answer & explanation
Correct answer: option 3
Given : -
Speed of man = 45 km/h
45 km/h = 45 × \(\frac{5}{18}\) = \(\frac{25}{2}\) m/sec
Time = \(\frac{Distance }{Speed }\)
= \(\frac{225 × 2}{25}\)
= 18 sec
