Bella runs 5.5 miles in 22 minutes. Jason runs 0.64 miles in two minutes. Who runs at a faster rate?
To compare the running rates of Bella and Jason, we can calculate their respective speeds (miles per minute).
Bella's speed = distance / time = 5.5 miles / 22 minutes = 0.25 miles per minute.
Jason's speed = distance / time = 0.64 miles / 2 minutes = 0.32 miles per minute.
Comparing their speeds, we can see that Jason runs at a faster rate than Bella.
