Answer :
4/5 mile per hour because 1/5 mile per 15 minutes, so 15 minutes x 4 = 1 hour, 1/5 mile x 4 = 4/5 mile
Solution:
we are given that
Parker walks 3/5 Mile in 45 minutes.
we have been asked to how many miles per hour does Parker walk.
since Parker walks 3/5 Mile in 45 minutes so it can be written as
[tex] \frac{3/5}{45} \frac{miles}{minute} \\
\\
\frac{3/5}{45} \frac{miles}{minute}=\frac{3}{5}*\frac{miles}{45/60 hr}\\
\\
=\frac{3}{5}*\frac{60}{45} miles/hr\\
\\
= \frac{3}{5}*\frac{4}{3} miles/hr\\
\\
=\frac{4}{5} miles/hr\\ [/tex]
