Comprehension Passage
Directions: Answer the questions based on the information given below.
The line graph given below illustrates the distances traveled (in km) by five different boats in the upstream and downstream directions over the same period of time.
The table provided below illustrates the sum of the still water speed and downstream speed (in km/hr) for each boat.
| Boats | Sum of the speed of boat in still water and downstream speed (in km/hr) |
|---|---|
| S | 60 |
| T | 56 |
| U | 95 |
| W | 60 |
| X | 100 |
When the speed of boat 'U' in still water is increased by 10% and the speed of the stream is increased by 20%, then how much less time does it take for boat 'U' to cover a distance of 91 km upstream compared to the original time taken by boat 'S' to cover the original given upstream distance?
