How Much Time will be Taken by the Motorcycle? if
Answer: (3) 9 min
Let the speed of a motorcycle is X km/hr.
A motorcycle is twice as fast as a car.
Then, the speed of car = 2 X km/hr.
The speed of a car is thrice as fast as scooter.
Then, the speed of scooter = 3 (2 X)
= 3 x 2 X
= 6 X km/hr.
The journey covered by scooter in 54 min.
Then, journey covered by motorcycle = 6 X = 54
X = 54/6
X = 9 min.
Then, the journey covered by motorcycle is 9 min.
Hence, the answer is (3) 9 min.
