Let speed of stream = x km/h
And,   speed of boat = 10 km/h
     Speed of the boat along upstream = (10-x) km/h  
 A/q,
      The boat goes  37.5 km opposite to the stream in 5 hours.
 speed = distance ÷ time
 speed of boat opposite to the stream = 37.5÷5
or,  10-x = 37.5/5
or,   x = 10-37.5/5
or,   x = (50-37.5)/5
or,   x = 12.5/5 = 2.5 km/h
Therefore speed of the stream = 2.5 km/h
