Question
The pie charts represent the distances covered by a boat moving upstream and downstream over seven days of a week. The total distance covered upstream is and downstream is . The percentages of distances covered each day are as follows:
The table below shows the speed of the stream (in km/hr) on different days:
| Day | Speed of Stream (km/hr) |
|---|---|
| Monday | 2 |
| Tuesday | 3 |
| Wednesday | - |
| Thursday | 1 |
| Friday | 2 |
| Saturday | - |
| Sunday | 4 |
If the time taken by the boat to travel upstream on Sunday is 2 hours more than the time taken by it to travel downstream on Thursday and the speed of the boat in still water on Thursday is 17 kmph, then find the upstream speed of the boat on Sunday.
