### Word Prblems (rate, time, and distance)

I am having a problem with this one...

The Clarke family went sailing on a lake. Their boat averaged 6 kilometers per hour. The Rourke family took their outboard runabout for a trip on the lake for the same amount of time. Their boat averaged 14 kilometers per hour. The Rourke family traveled 20 kilometers farther than the Clarke family. How many hours did each family spend on their boat trip?

How much further did the second group travel, in each hour, than did the first group? How many hours would it take to get twenty miles ahead? (You'll have to use a half-hour to complete the answer.)
