A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is:
Answer: Option
Explanation:
Man's rate in still water = (15 - 2.5) km/hr = 12.5 km/hr.
Man's rate against the current = (12.5 - 2.5) km/hr = 10 km/hr.

MS with CS = 15.
CS = 2.5,
MS = 15-2.5= 12.5.
Against means Opp direction so it is Upstream For this MS - CS so 12.5 -2.5 = 10.
CS = 2.5,
MS = 15-2.5= 12.5.
Against means Opp direction so it is Upstream For this MS - CS so 12.5 -2.5 = 10.

What is the formula of boat and stream? Please explain to me.

The speed of the boat is always mid-value.
The speed of the stream is the difference between upstream and downstream.
Boat speed upstream+downstream divided by 2.
The speed of the stream = upstream-downstream divided by 2.
The speed of the stream is the difference between upstream and downstream.
Boat speed upstream+downstream divided by 2.
The speed of the stream = upstream-downstream divided by 2.

Here they did not mention that is/clearly not questioned that this is a boad and stream problem.

Given that mans speed with current means mans speed+current = 15, So here current is given from which we get actual speed of man is 12.5km/hr, Then he asked against the current so the answer will be 12.5 - 2.5=10km/hr.
