Question

I jogged for 3 2/5 miles in 7/8 hours what average speed in miles per 1 hour

Answer 1

`formula\ for\ average\ speed:\\ speed=(distance)/(time)\\\\ (3(2)/(5))/((7)/(8))(miles)/(hours)=(17)/(5)*(8)/(7)=(17*8)/(5*7)=\\\\ (136)/(35)=27,2(miles)/(hour)\\\\ \boxed{Solution\ is\ v=27,2(miles)/(hour)}`
