Answer 2

We have been given that the upstream speed is and the down stream speed is .

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is

Time upstream + time downstream = 6

lcm = 10

=>

Cross multiplying,

x = 20 miles .. Answer.
