Set it up as a proportion. 14.25 miles is to 90 minutes as x is to 120 minutes.

We have to solve with like units of measure, so we have to change the hours to minutes before we can set up the proportion.

60 minutes= 1 hour
120 minutes = 2 hours

x= miles in 2 hours

14.25/90 = x/120
cross multiply
(14.25 * 120)= (90 * x)
1710=90x
divide both sides by 90
19= x

You could ride 19 miles in 120 minutes, so you could ride 19 miles in 2 hours.

Did you need help on #2 also?

Hope this helps! :)
