Question

In 25 minutes, Jay can run 10 laps around the track. Write an equation to represent the relationship.

A) y = .2/5x
B) y = .5/2x
C) y = x + 2/5
D) y = x+ 5/2

Answer 1

A

Explanation:

Answer 2

The equation is
`y=(2)/(5) x`.

Explanation:

Let
`y` represent the number of laps Jay run, and
`x` the number of minutes it takes him to run those laps.

We know that it it takes Jay 25 minutes to run 10 laps; therefore, the number of laps jay runs per minute is:

`(10\:laps)/(25\:minutes) =(2)/(5)\:laps/min`

So, if Jay runs for
`x` minutes, the number of laps
`y` he will run be:

`\boxed{y=(2)/(5)x}`
