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 \[=\frac{1}{22}\times 11000=500\]revolutionsYou need to login to perform this action.
