Question

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

Answer 1

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