The speed of a car is 36 km/h. How much time(in minutes) will a bus traveling at one-fifth of the speed of the car take to cover a distance of 900 m?
Answer & explanation
Correct answer: option 2
Speed of car = 36 km/h
36 km/h = 36 × \(\frac{5}{18}\) = 10 m/sec
According to question , Speed of bus = \(\frac{1}{5}\) × 10 = 2 m/sec
Time taken to cover 900 m = \(\frac{DIstance}{Time}\)
= \(\frac{900}{2}\) = 450 sec
= 7.5 minutes
