You can put this solution on YOUR website!
In terms of just units:
( feet / sec ) x ( sec/min ) x ( min/hr ) x ( miles/ ft ) = miles / hr
To check you can rewrite it like this:
( ft/ft ) x ( sec/sec ) x ( min/min ) x ( miles/hr ) = miles/hr
--------------
+%28+110%2F5+%29%2A%28+60%2F1+%29%2A%28+60%2F1+%29%2A%28+1%2F5280+%29+
+22%2A60%2A60%2A%28+1%2F5280+%29+
+79200+%2F+5280+=+15+
The boat's speed is 15 mi/hr
