SOLUTION: If I ran 0.24 miles how much more must I run to reach 1.5 miles? Also, in Oder to run 1.5 miles in 15 minutes how fast should I run per minute?

Put 0.24 under 1.5 miles and subtract:

1. Make sure the numbers are lined us so that the decimal of 0.24
is directly under the decimal of 1.5, like this:

                         1.5  miles
                        -0.24 miles

2. We have to make the top number have as many decimal places as the
bottom number, so we put on a 0 after the 1.5, like this:

                         1.50 miles
                        -0.24 miles

Then we subtract as usual:

                         1.50 miles
                        -0.24 miles
                         1.26 miles
