You first have to plug in your given numbers to the equation.
d= rt
d=(52)4.5
Then you solve
52*4.5 = 234
So, your distance or d=234
Something that could be done is to tie a rope long enough to cross the river and send the two younger brothers across first, then have Mike pull the boat back across the river with the rope and him get in the boat and row it across the river with just himself and the gear.

Hope this helps!
