How long, in minutes, did it take a bicycle wheel to roll along a flat, straight 300-meter path?
(1) The wheel made one full 360-degree rotation every 1.5 meters.
(2) The wheel made 18 360-degree rotations per minute.
The OA is C.
A solution can be as follows,
T= time taken to cover the entire distance
V= velocity
W= frequency = rev per sec
R= radius of wheel
Distance (300)= v * T = (wr)* T
Now w is given in second statement
And r is given in first statement
Hence C is the correct answer.
Has anyone another strategic approach to solving this DS question? Regards!
