Aman who can row in still water at 3 mph heads directly across a river flowing at 7 mph. at what angle to the line on which he is heading does he drift downstream (nearest degree)? 23° 50° 67°

If the velocity of the rower is V1=3mph and velocity of the river is V2=7mph and

V1 ⊥V2 then

tanα=7/3 => tanα ≈ 2.33 => α≈ 66.8° ≈ 67°

The correct answer is 67°

Good luck!!!
