Question

Maria had planned to walk 10 1/8 miles on wednesday, if she walked 7 2/8 miles in the morning how far would she need to walk in tge afternoon ?

Answer 1

Distance Maria had to walk in the afternoon is
`2(7)/(8)`

Explanation:

Lets take that Maria walked
`x` miles in the afternoon.

Distance walked in the morning + distance walked in the afternoon =
`10(1)/(8)`

⇒
`7(2)/(8) +x=10(1)/(8)`

`(58)/(8) +(8x)/(8) =(81)/(8)`

`(58+8x)/(8) =(81)/(8)`

`58+8x=81`

`8x=81-58\\`

`8x=23`

`x=(23)/(8)`

`x=2(7)/(8)`
