Answer 1

12.7 units

Explanation:

Formula to get the distance between the two points
`(x_1,y_1)` and
`(x_2,y_2)` is,

d =
`√((y_2-y_1)^2+(x_2-x_1)^2)`

From the picture attached,

Sherry is at the origin(0, 0) and going to the top (12, 4)

Distance between these points will be,

d =
`√((12-0)^2+(4-0)^2)`

d =
`√(160)`

d =
`4√(10)`

≈ 12.7 units

Therefore, Sherry has to travel 12.7 units on the ramp.
