Question

1 point 3 John ran 3 les in of an hour Marlon ran s 4 miles in of an hour How lar did Marlon run in one hour?

Answer 1

6.2 miles per hour

Step-by-step explanation:

Marlon ran 8 1/4 miles in 4/3 of an hour.

So, we first need to transform the mixed number 8 1/4 into a fraction using the following equation:

`\begin{gathered} A(b)/(c)=(A\cdot c+b)/(c) \\ 8(1)/(4)=(8\cdot4+1)/(4)=(32+1)/(4)=(33)/(4) \end{gathered}`

Then, we need to divide 33/4 miles by 4/3 hour as:

`\begin{gathered} ((a)/(b))/((c)/(d))=(a\cdot d)/(b\cdot c) \\ ((33)/(4))/((4)/(3))=(33\cdot3)/(4\cdot4)=(99)/(16)=6.2\text{ miles per hour} \end{gathered}`

So, Marlon ran 6.2 miles per hour.
