Answer:
Fisherman traveled 14.4 miles.
Step-by-step explanation:
A fisherman's downstream speed = 6 mph
and upstream speed = 4 mph
Let the fisherman traveled x miles he travels upstream.
Time spent in travelling x miles =
hours [Since time =
]
Similarly when fisherman covers x miles down stream
Time spent in x miles =
hours
Now total time in going upstream and downstream is 3 hours then

x

5x = 12×3
5x = 36
x =
miles.
Since fisherman has traveled 2x distance so the answer will be 14.4 miles
Therefore, fisherman traveled 14.4 miles.
