Debra can run 20 1/2 miles in 2 1/4 hours. How many miles per hour can she run?

Answer:She can run [tex]\frac{82}{9}* \frac{miles}{hour}[/tex]Step-by-step explanation:It is required to estimate the velocity of Debra.Debra can run 20 1/2 miles. It means d = 20 1/2 miles = 41/2 miles.Debra runs the distance previously presented in 2 1/4 hours. It means t = 2 1/4 hours = 9/4 hours.Now, we have the distance (d), and the time requiered (t) in which Debra can run. Finally, to calculate the velocity we need to divide the distance by the time. [tex]v = \frac{d}{t}\\\\v =\frac{\frac{41}{2}}{\frac{9}{4}} = \frac{41*4}{2*9}=\frac{82}{9}\\v =\frac{82}{9} \frac{miles}{hour}[/tex]Debra can run 82/9 miles per hour.
