A train running at 7/11 of its normal speed reached a place in 22 hours.
Formula Used:
Time saved = Time taken at reduced speed - Time taken at normal speed
Calculation:
Let the normal speed of the train be .
Time taken at reduced speed = 22 hours
Speed at reduced speed = (7/11)S
Distance = Time taken at reduced speed × Speed at reduced speed
Distance = 22 × (7/11)S
Distance = 14S
Time taken at normal speed = Distance / Normal speed
Time taken at normal speed = 14S / S
Time taken at normal speed = 14 hours
Time saved = Time taken at reduced speed - Time taken at normal speed
Time saved = 22 - 14
Time saved = 8 hours
The correct answer is option 3.
