Answer: 10 miles after 5 track practices.
Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.
8/4 converted to a unit rate is 2/1
The unit rate is 2 miles per every 1 track practice.
We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.
2/1 x 5 = 10/5
So, Leslie would have ran 10 miles after 5 track practices.
