To find Lauren's unit rate, we need to divide the total distance she jogs by the total time it takes her. Lauren jogs at a rate of 2 miles every 2/5 hour. To find the unit rate, we divide the distance (2 miles) by the time (2/5 hour):
Unit rate = 2 miles / (2/5 hour)
Dividing by a fraction is the same as multiplying by its reciprocal:
Unit rate = 2 miles x (5/2 hour)
When we multiply straight across, the hours cancel out, leaving us with the unit rate:
Unit rate = 5 miles / 2 = 2.5 miles per hour

Lauren jogs at a unit rate of 5 miles per hour. This was calculated by determining how many miles she runs in one hour based on her given pace. By setting up a proportion and solving for the unknown, we found the unit rate to be 5 mph.
