<span>Hollis travels 0.05 miles per minute faster than Charmaine.
First, convert to the same units for both Hollis and Charmaine. So Hollis takes 18.5 minutes and Charmaine takes 0.5*60 = 30 minutes. Both girls travel 2.4 miles, so calculate how many miles per minute each takes
Hollis = 2.4 / 18.5 = 0.13 miles per minute.
Charmaine = 2.4 / 30 = 0.08 miles per minute.
Finally determine the difference in speed between the two girls.
0.13 - 0.08 = 0.05 miles per minute.</span>
