Center Console Boats And More

How am I supposed to do this algebra word problem?

1.) A fishing boat traveled 3 hours against a 6 kph current. The return trip took only 2 hours. Find the speed of the boat in still water.
2.) One leg of a right triagle is 5 times the other leg. Find the longer leg if the hypotenuse is 60 ft.

My school starts tomorrow and I have to finish 14 word problems which I suck at. :) Thanks sooooooooooooooo much for your help!
