In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour. Using this information, which inverse variation could you use to determine his speed if he covers the 216 miles in different amounts of time?

Step-by-step explanation:

In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.

Speed is inversely proportional to the time taken

speed is 18 miles per hour and distance is 216 miles

Let 's' be the speed and 't' be the different time

Replace distance by 216

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

6.5

you said it was in the question
