Given Equation: Speed of boat in still water =10 km\hr
Boat Travels a distance of 37.5 km in time 5 hr.
Factor to consider speed of stream be 's'
According to the formula:
Speed =
Time
Distance
Total speed = speed of boat in still water and speed of stream
Since the boat travels upstream
Total speed = Speed of boat in still water - speed of water in stream
10−s=
5
37.5
10−s=7
