If a man travels at 7 / 11th of his usual speed the time taken by him is what percentage of the usual time taken to cover the same distance? Correct Answer 157%
The fraction of time taken is reciprocal of the fraction of speed. The time taken = 11 / 7th of the usual time taken = 11 / 7 * 100% of the usual time taken = 157.142% ≈ 157%
