Answer:
Average speed is in distance over time, so you could write:
1.5 miles / 10 minutes
Now, simplify:
.15 miles per minute
Step-by-step explanation:
[tex]\bf \begin{array}{ccll} project&hours\\ \cline{1-2} \frac{1}{10}&\frac{3}{5}\\\\ x&1 \end{array}\implies \cfrac{~~\frac{1}{10}~~}{x}=\cfrac{~~\frac{3}{5}~~}{1}\implies \cfrac{~~\frac{1}{10}~~}{\frac{x}{1}}=\cfrac{3}{5}\implies \cfrac{1}{10}\cdot \cfrac{1}{x}=\cfrac{3}{5} \\\\\\ \cfrac{1}{10x}=\cfrac{3}{5}\implies 5=30x\implies \cfrac{5}{30}=x\implies \cfrac{1}{6}=x[/tex]
