Question

Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone. Let D represent the distance (in meters) from the safe zone after t seconds. Complete the equation for the relationship between the distance and number of seconds.

Answer 1

y=-25x+160

Explanation:

Answer 2

`d=160-25t`

Explanation:

Let
`d` be the distance between Kayden and safe zone at any time.

It is given that initially
`d=160`

Lrt her speed be
`v`

Since the speed is constant,the distance covered by her in
`t` seconds=
`v* t`

So,the distance between her and safe zone after
`t` seconds is
`160-vt`

It is given that after
`3` seconds,
`d=85`

So,
`160-3v=85`

`3v=75`

`v=25`

So,
`d=160-3t`
