A proportional relationship is a relationship between equivalent ratios. Imagine that ice cream costs $2 per scoop. If you get one scoop of ice cream, you'll pay $2. If you get two scoops, you'll pay $4, and for three scoops you'll pay $6. These ratios of scoops to prices are equivalent. Therefore, the relationship between number of scoops and total price is proportional. To find out the total price of your ice cream, you can always multiply the number of scoops you're getting by the same number, 2. Which of these can be described with a proportional relationship? А:An athlete runs 1 mile in 7 minutes and another mile in 7.5 minutes. B: An athlete does 10 push-ups for every 1 mile she runs. C: An athlete runs 2 miles and does 25 push-ups. D: An athlete runs 5 miles 3 times a week.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
