A young adult female is running a 24 mile course. If she runs the first 6 miles in one hour, the second 6 miles in 1.2 hours, the third 6 miles in 1.5 hours, and the fourth 6 miles in 1.6 hours, how long will it take her to complete this 24 mile run? (Enter numeric value only. If rounding is required, round to the nearest tenth.

The ratio of females to students enrolling to nursing school is 7:8. So the percent of girls in the class is:

\(\frac{7\ }{8\ }\ast100\%\ =\ 87.5%\)

Therefore, the class is made of 87.5% of females enrolling to a nursing school

First convert 8 ¼ to improper fraction as

\(8\frac{1}{4}=\frac{\left(8\ast4\right)+1}{4}=\frac{32+1}{4}=\frac{33}{4}\)

Use 1 pint =16 ounces to convert between pints and ounces

\(\frac{33}{4}\ pints\ast\frac{16 ounces}{1 pint}=132 ounces\)

If the woman cuts her consumption by 75%, then she consumes 25% (100-75) of coffee. Then, the number of cups allowed to drink

\(\frac{25}{100}\ast5\ cups=1.25\ cups\)

The number of ounces of coffee she is allowed to drink is:

\(\frac{1.25\ cups\ast8 ounces}{1 cup}=10 ounces\)

The number of packets of a balloon to purchase is evaluated as follows

\(16\ children\ast\frac{15 balloons}{1 child}\ast\frac{1 packet}{50 balloons}=\frac{24}{5}=4.8 packets\)

Approximating 4.8 to 5, the mother will have to buy 5 packets of balloons.
