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 y represent the distance (in meters) from the safe zone after x seconds.

Complete the equation for the relationship between the distance and number of seconds.

Answer 1

Answer: y = 160 - 25x

Step-by-step explanation: thats the answer on khan

Answer 2

The required equation is
`y=160-25x`.

Explanation:

Consider the provided information.

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.

The distance from the safe zone = 160 meters,

And, after 3 seconds she is 85 meters far away from the safe zone,

Distance cover in 3 seconds = 160 - 85 = 75 meters,

As we know:
`Speed=(Distance)/(Time)`

`Speed=(75)/(3)=25`

Hence, her speed is 25 meter per second.

Let y represent the distance (in meters) from the safe zone after x seconds.

`y=160-25x`

Hence, the required equation is
`y=160-25x`.
