Question

Marneshire walked 3/8 of a mikes in 3/5 of an hour. What equation can be used to calculate her unit rate in miles per hour

Answer 1

`\bf m=\cfrac{rise}{run}\implies \cfrac{\quad (3)/(8)~mile\quad }{(3)/(5)~hour} \\\\\\ m=\cfrac{\quad (3)/(8)\quad }{(3)/(5)}\implies m=\cfrac{\underline{3}}{8}\cdot \cfrac{5}{\underline{3}}\implies m=\cfrac{5~miles}{8~hour}\implies m=0.625~(miles)/(hour)`
