Question

Yesterday, Asher ran 2 miles in nineteen minutes. Today, he ran 3 miles in thirty minutes. The function that describes the relationship between the number of miles he ran and the time he ran is a linear function. How long will he run tomorrow if he runs 5 miles? Explain.

Answer 1

Now that you have slope, use the slope equation: y = mx + b.
y = mx + b
y = 11x + b
Now plug in x and y . I'm choosing (3, 30)
30 = 11(3) + b
30 = 33 + b
b = -3

Now that you have b , plug back to original equation:
y = 11x - 3

The problem is asking for 5 miles, so x = 5 miles
y = 11(5) - 3
y = 55 - 3
y = 52 minutes.

She will run 5 miles in 52 minutes the next day.
