Speed of boat in water = 5km/h
Let the speed of stream be = x km/h
So, the speed of the boat upstream will be - (5-x) km/h
And the speed of boat downstream will be - (5+x) km/h
Time given to cover 40km upstream = 3(time taken to cover downstream)
40/5x km/h = 3(40/5+x)
120/5 +x = 40/5-x
600 - 120x = 200 + 40x
600-200m= 120x + 40x
400 = 160x
Therefore, x = 400/160
= 2.5
Hence, speed of stream = 2.5
Hope my answer helps you. Please mark as brainliest.
