In how much time can a person cover a distance of 300 metres at a speed of 27 km/h?
Answer & explanation
Correct answer: option 1
Speed = 27 km/h
27 km/h = 27 × \(\frac{5 }{18 }\)m/sec = \(\frac{15 }{2 }\) m/sec
Total distance = 300 m
Time taken = \(\frac{Distance }{Speed }\)
= \(\frac{300 × 2 }{15 }\)
= 40 sec
