The speed of a boat in still water is 8 km/hr. If its speed downstream be 15 km/hr, then speed of the stream is ?

7.5 km/hr

7 km/hr

9 km/hr

None of these

We know that:-

Downstream Speed = Boat's Speed + Water's Speed

15 km/hr = 8 km/hr + Water's Speed

Water's Speed = 15 - 8 = 7 km/hr [Here Stream's Speed = Water's Speed]
