Wait it says ur in high school so u can't be over 30. that isn't possible. So what's the problem here? not good at math.
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 
Hence, 
Time upstream + time downstream = 6
lcm = 10
=> 
Cross multiplying, 
x = 20 miles .. Answer.
Answer:
-8.
Step-by-step explanation:
That would be change in height divided by change in time:
= (40 - 80) / (5 - 0)
= -40 / 5
= -8.
