Question

The jogging track at Francine’s school is 3/4 mile long. Yesterday Francine completed two laps on the track. If she ran 1/3 of the distance and walked the remainder of the way, how far did she walk?

Answer 1

i dont know but mabye is 2/3

Answer 2

1 mile

Explanation:

Given: The jogging track at Francine’s school is
`(3)/(4)`
`\text{mile}` long. Yesterday Francine completed two laps on the track. If she ran
`(1)/(3)` of the distance and walked the remainder of the way.

To Find: how far did she walk

Solution:

Length of jogging track at Francine’s school
`=(3)/(4)`
`\text{mile}`

Let the distance covered by running be
`=\text{x}`

Let the distance covered by walking be
`=\text{y}`

Total number of laps completed by Francine
`=2`

Total distance covered by Francine
`=\text{number of laps}*\text{distance covered in one lap}`

`2*(3)/(4)`

`(3)/(2)\text{mile}`

Now,

distance covered by running
`=(1)/(3)\text{of total distance}`

`\text{x}=(1)/(3)*(3)/(2)`

`\text{x}=(1)/(2)`
`\text{mile}`

distance covered by walking
`\text{y}`
`=\text{total distance}-\text{distance covered by running}`

`(3)/(2)-\text{x}`

`(3)/(2)-(1)/(2)`

`1`
`\text{mile}`

Hence, Francine walked for
`1`
`\text{mile}`
