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.
\n" ); document.write( "
There are 2 boat speeds: one going downstream, and the other going upstream.
\n" );
document.write( "Let the speed of the current be C
\n" );
document.write( "Then we get the following TIME equation: \"matrix%281%2C3%2C+15%2F%2816+%2B+C%29%2C+%22=%22%2C+9%2F%2816+-+C%29%29\"
\n" );
document.write( "Solve the above for C, the current.
\n" );
document.write( "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. \n" );
document.write( "
\n" );
