Question

Elena's distances and times for a training run are given by the equation y = 8.5x, where x represents distance in miles and y represents time in minutes.
Who ran farther in 10 minutes ? How much farther? Explain how you know.

Answer 1

Answer:

Elena ran 1.17 miles farther than others in 10 minutes

Step-by-step explanation:

y=8.5x

x is Dist, and  y is time. Given that y is 10, we may find Dist (x) as-

10=8.5 X (divide both sides by 8.5)

10/ 8.5 = X

X=1.17 miles

Answer 2

Answer: He ran 1.176 miles in 10 minutes.

Step-by-step explanation:

Since we have given that

$y=8.5x$

Here, x is the distance in miles.

y is the time in minutes

Here, y = 10 minutes

According to question, we get that

$10=8.5x\\\\x=\dfrac{10}{8.5}\\\\x=1.176\ miles$

Hence, he ran 1.176 miles in 10 minutes.
