Question

Jen's goal is to run a total of 22 miles in five days. The table below shows her log for the number of miles she ran on Monday, Tuesday,Wednesday, and ThursdayHow many miles must Jen run on Friday to reach her goal?

Answer 1

Given that Jen's tota run should be equal to 22 miles.

Let she ran 'x' miles on Friday. Then the sum of the number of miles for each day must be equal to 22 miles,

`\begin{gathered} 4(3)/(4)+5(1)/(8)+0+6(1)/(4)+x=22 \\ (19)/(4)+(41)/(8)+(25)/(4)+x=22 \\ (38+41+50)/(8)+x=22 \\ (129)/(8)+x=22 \\ x=22-(129)/(8) \\ x=(176-129)/(8) \\ x=(47)/(8) \\ x=5(7)/(8) \end{gathered}`

Thus, she must run 5 whole 7/8 miles on Friday, in order to reach her goal.
