Question

Elena's distances and times for a training run are given by the equation , where represents distance in miles and represents time in minutes. Who ran faster during the training run?

Answer 1

Elena's run for 1.17 miles in ten minutes

Explanation:

From the question

y = 8.5 x ; where x is Distance in miles, and y is time in minutes

and y= 10 minutes

thus on substituting the respected values we get

10 = 8.5 x

⇒ x =
`(10)/(8.5)` = 1.17 miles

Therefore Elena's run for 1.17 miles in ten minutes
