Fred can run 12 miles in 1 hour and can bike 30 miles in 2 hours. What percent of Fred's average biking speed is his average running speed?

first thing you have to do is find the rate for the bike so you divide 30 by 2 and you get 15 after you do that you make a problem to find the percentage so you take x/100 and 12/15 then you take 12 times 100 and that gives you 1200 then you divide by 15 and get 80. So the answer is 80%
