Answer:
21.2 miles Sophia had run before she was pass by Josefina.
Step-by-step explanation:
As Josefina started after 25 minutes , so in 25 minutes Sophia had traveled (4.8* (25/60) ) 2 miles. Now the difference between their speed is (5.3-4.8) 0.5 miles. so it will require (miles/ difference in speed, 2/0.5) 4 hours for Josefina to pass Sophia.So by that time Sophia has traveled for 4 hours & 25 minutes.
Now multiply it with her speed 4.8 (4 *25/60)= 21.2 miles.
