Question

Samantha walks a total of 2/3 mile to get to and from school each day. Write an expression that can be used to find the total number of miles that Samantha walks to and from school over 5 days. Then evaluate the expression.

Answer 1

For this case we have:

Let y the variable that represents the number of miles Samantha walks according to school days (represented by varibale x)

So:

`y = \frac {2} {3} x`

If we have that samantha walks 5 days, then we substitute
`x = 5`.

`y = \frac {2} {3} (5)\\y = \frac {10} {3}`

So, Samantha walks \
`\frac {10} {3}`miles for 5 days, to go to and from school.

Answer:

`\frac {10} {3}`
