Asked by big guy
A coach is comparing data about the number of miles Jacob and Otto jogged and the time they spent jogging on week days.
Jacob jogged 3 miles in 30 minutes on Wednesday and 5 miles in 50 minutes on Thursday. Otto jogged 4 miles in 32 minutes on Wednesday and 6 miles in 50 minutes on Thursday.
Whose data shows a proportional relationship between the number of miles jogged and the time spent jogging?

Jacob's data is proportional.
Check the ratios (miles per minute or minutes per mile):
- Jacob: 3/30 = 1/10 and 5/50 = 1/10 (same ratio → proportional).
- Otto: 4/32 = 1/8 = 0.125 and 6/50 = 0.12 (different → not proportional).
