Given:
Alyssa R. ran 24 miles more than Fidha
Alyssa ran 39 miles
Let the number of miles Fidha run be x
From the given statements, we can write the sum of the number of miles Fidha ran plus the extra miles covered by Alyssa R. should be equal to the number of miles ran by Alyssa
Solving for x:
Hence, the number of miles Fidha ran is 15 miles
Answer: 15 miles
