A1.55m tall fisherman stands at the edge of a lake, being watched by a suspicious trout, which is 3.50 m from the fisherman in the horizontal direction and 45.0 cm below the surface of the water. at what angle from the vertical does the fish sees the top of the fisherman's head? (index of refraction for water is 133. use numerical solution or trial-and-error method).

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
