Question

Ashley complete 1/10 of the project in 3/5 of hour. What fraction of the projection Ashley complete in 1 hour

Answer 1

`\bf \begin{array}{ccll} project&hours\\ \cline{1-2} (1)/(10)&(3)/(5)\\\\ x&1 \end{array}\implies \cfrac{~~(1)/(10)~~}{x}=\cfrac{~~(3)/(5)~~}{1}\implies \cfrac{~~(1)/(10)~~}{(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`

Average speed is in distance over time, so you could write:

1.5 miles / 10 minutes

Now, simplify:

.15 miles per minute
