    The radius of a circular wheel is 3.5m. How many revolutions will it make in travelling 11 km?

    A)  575                             

    B)  620                 

    C)  500                 

    D)         415                 

    E)  None of these

    Correct Answer: C

    Solution :

    Distance travelled\[\text{=11}\,\,\text{km = 11000m}\] Radius of wheel\[=3.5\,\,m\] \[\therefore \]Circumference of wheel\[=2\times \frac{22}{7}\times 3.5=22\,\,m\] \[\therefore \]In travelling 22m, the wheel makes 1 revolution. \[\therefore \]In travelling 11000m, the wheel makes \[=\frac{1}{22}\times 11000=500\]revolutions
