Question

Hello I need help with this practice problem I don't know how to convert it to miles?

Answer 1

Answer:

The correct options are B and D

B. Eagle ride 2 times

D. Black Bear 1 time, Doe Run 2 times

Step-by-step explanation:

To know the correct option, we need to test each of the options to see which one would be 25 miles or less.

1. Doe run 3 times

`\begin{gathered} 3*8(3)/(4) \\ \\ =3*(35)/(4)=(105)/(4) \\ \\ =26(1)/(4)\text{ (FALSE)} \end{gathered}`

2. Eagle ride 2 times

`\begin{gathered} 2*10(1)/(4)=2*(41)/(4)=(41)/(2) \\ \\ =20(1)/(2)\text{ (TRUE)} \end{gathered}`

3. Black Bear 2 times, Eagle ride 1 time

`\begin{gathered} 2*7(1)/(2)+10(1)/(4) \\ \\ =25(1)/(4)\text{ (FALSE)} \end{gathered}`

4. Black Bear 1 time, Doe Run 2 times

`\begin{gathered} 7(1)/(2)+2*8(3)/(4) \\ \\ =25\text{ (TRUE)} \end{gathered}`

The correct options are B and D
