Question 1134473
A boat travels at 16 mph in still water. It takes the same amount of time for the boat to travel 15mi downstream as to go 9 mi upstream. Find the speed of the boat.
<pre>There are 2 boat speeds: one going downstream, and the other going upstream.
Let the speed of the current be C
Then we get the following TIME equation: {{{matrix(1,3, 15/(16 + C), "=", 9/(16 - C))}}}
Solve the above for C, the current.
ADD the value of C to 16 to get the downstream speed and SUBTRACT the value of C from 16 to get the upstream speed.
