Let x be the unknown distance from his scout camp to another camp. The time it takes for him to travel upstream is x / (5 + 3) and downstream x / (5 - 3)
The total time for him to travel forth and back is 10 hr. This may be mathematically expressed as,
x/8 + x/2 = 10
Solving for x in this equation gives 16. Thus, the distance to the camp is 16 miles.
