Phil is riding his bike. He rides 21 miles in 2 hours, 31.5 miles in 3 hours, and 42 miles in 4 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 =

hi

Step-by-step explanation:

Constant of proportionality: 10.5  or k= 10.5

y= 10.5x

Step-by-step explanation: You will take your y/x value, which in this case is miles per hour. So you will do each of your miles per hour.

21/2= 10.5

31.5/3= 10.5

42/4= 10.5

Therefore your constant of proportionality is 10.5.
