A swimmer crosses the river along the line making an angle of 45º with the direction of flow. Velocity of the river water is 5 m/s. Swimmer takes 6 seconds to cross the river of width 60 m. If the velocity of the swimmer with respect to water is 
m/s, then find n.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION
(5)
Sol. 
= 
+ 
As resulting velocity 
is at 45° with river flow
i.e. 
– 
sin α = 
cos45° ...........(i)
and 
= 6 sec. ...........(ii)
Solving &
V m, r = 5 
m/s
