A motorcycle stunts man belonging to a fair, rides over the vertical walls of a circular well at an average speed of 54 kph for 5 minutes. If the radius of the well is 5 meters then the distance traveled(in kilometers) is:
-
4.5 kms
-
5 kms
-
7.5 kms
-
6 kms
A
Correct answer
Explanation
Distance = Speed × Time. Speed = 54 kph, Time = 5 minutes = 5/60 hours = 1/12 hours. Distance = 54 × (1/12) = 4.5 km. The radius of the well (5 meters) is extra information not needed for this calculation. The question tests whether you can identify the relevant variables and perform the unit conversion correctly.
