Total distance travelled =( 54 /60) x5 = 4.5 kms. It doesn't matter what is the radius of the well as we can easily calculate distance with time and velocity.harsh.champ wrote: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.

Do we really need the radius in this question? we have the speed and the time, distance can be calculated without the radius.harsh.champ wrote: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.

Looks as if the radius is completely unnecessary, makes the question a little weird, or maybe I should say a little weirder as also "rides over the vertical walls" is funny way of putting what I think it means.
