Question
Sheila can walk in the speed of her normal speed (16/17)
and fix a certain distance in 5 minutes more than the normal speed. Calculate the normal time it takes in determining a certain distance? (in a minute)Solution
Let the speed of the Sheila be 17x. Speed of the Sheila after decrement = 17x × 16/17 = 16x Speed ratio of normal speed to reduced speed = 17x: 16x The time ratio of normal time to increased time = 16x: 17x The extra time she will take due to reduced speed, 17x - 16x = x x = 5 min Normal time taken by her,  16x = 5 x 16 = 80 min The total time taken by Sheila at normal speed was 80 min.
