Answer:
Step-by-step explanation:
To solve such questions always keep one thing in mind that if the boat moves with the flow of water, the speed of the boat will increase from its original speed and if the boat moves against the flow of water then the speed of the boat will reduce from its original speed.
Let the speed of boat be = x
speed of water current = y
Therefor-:
Speed of the boat while moving with the current = x+y
Speed of the boat while moving against the current = x-y
Distance = Speed × Time
30 = (x+y) × 6 ------[Eq (i)]
30 = (x-y) × 10 ------[Eq(ii)]
On solving both the equations-:
Speed of boat (x) = 4 km/h
Speed of water current (y) = 1 km/h
