Answer 1

hi frnds , :))
_______________________________

let man's speed = x
current speed = 2.5 km / h..........(given)

A/Q :-
x+2.5= 15
x= 15-2.5
= 12.5

hence man's speed will be 12.5 km / h

man's speed against current = 12.5 - 2.5
= 10

hence , ur answer is 10 km/h

hope it helped u

Answer 2

Total speed of both man and current is
15kmh. (This is given in question)
Let speed of man be. x
So
Speed of man and speed of current is 15.
We given speed of current is 2.5kmh
Then apply this,
X plus 2.5 =15
X=15-2.5
X= 12.5 and.
