In a river where the current is 5 miles per hour, it takes her 4 hours longer to row a given distance upstream than to travel the same distance downstream. Find how long it takes her to row upstream, how long to row downstream, and how many miles does the row one way

Let distance be D
\n" );
document.write( "Then time taken to row upstream is: , or 
\n" );
document.write( "Time taken to row downstream is: , or 
\n" );
document.write( "Since upstream time takes 4 hours longer than downstream time, then we get:
\n" );

document.write( "3D – D = 60
