The track team plans to sprint 20 miles this school year. The runners will sprint 1/4 mile each day. How many days will it take them to sprint 20 miles?

It will take the track team 80 days to sprint 20 miles.

This can be calculated by dividing the total distance to be sprinted (20 miles) by the distance sprinted each day (1/4 mile):
20 miles / (1/4 mile) = 80 days.
