Question 366331
let x be the distance he can travel to complete trip in 3 hours
downstream speed = 3+2 = 5mph
upstream speed = 3-2 = 1mph
time downstream + time upstream = 3 hours

x/5  + x = 3
6x/5 =3
6x=15
x= 2.5 miles.
..
speed downstream = 5 mph
distance = 2.5 miles
time downstream = 5/2.5 = 2 hours
