The diameter of a wheel is 98 cm. The number of revolutions in which it will have to cover a distance of 1540 m is
-
- 500
- 600
- 700
- 800
- 500
Correct Option: A
Using Rule 7,
Distance covered by wheel in one revolution = circumference of the wheel
| = π × diameter = | × 98 = 308 cm | |
| 7 |
| ∴ Number of revolutions = | = 500 | |
| 308 |
