Phil is riding his bike. He rides 58 miles in 4 hours, 72.5 miles in 5 hours, and 87 miles in 6 hours. Find the constant of proportionality and write an equation to describe the situation. Let x represent the number of
hours.
The constant of proportionality is k =
The equation that describes the relationship is y =

Constant = 11.5

y = 11.5x.

Step-by-step explanation:

This is direct variation so the equation of proportionality is

y = kx where y = miles, x = hours and  k is a constant.

23 =  2k

k = 11.5

34.5 = 3k

k = 11.5

46 = 4k

k = 11.5

The equation is my= 11.5x.

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
