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 1800 km1800 \text{ km} and downstream is 1500 km1500 \text{ km}. The percentages of distances covered each day are as follows:

If the time taken by the boat to travel upstream on Monday is 4511\frac{45}{11} hours more than the time taken to travel downstream on the same day, then find the speed of the boat in still water on Monday.
