Su = ?
Sd = 15km/hr,
Sd = x+ y.
x+ y = 15km/hr,
x + 2.5 = 15km/hr,
x = 12.5.
x = speed of man in still water.
Sd = x -y.
15- 2.5 = 10km/hr.
Sd = 15km/hr,
Sd = x+ y.
x+ y = 15km/hr,
x + 2.5 = 15km/hr,
x = 12.5.
x = speed of man in still water.
Sd = x -y.
15- 2.5 = 10km/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.
