Answer: Distance she ran on Thursday = 2.38 miles
Explanation:
Given, Amille ran on Monday = 2.36 miles
On Tuesday, she ran 4.88 miles.
On Wednesday, she ran 3.19 miles.
Total distance she ran till Thursday = 12.81 miles.
Now, Distance she ran on Thursday = (Total distance) - (Distance ran on Monday to Wednesday)
= 12.81-(2.36+4.88+3.19)
= 12.81-10.43
= 2.38 miles
Hence, Distance she ran on Thursday = 2.38 miles
