Answer:
In 3 hours Jada walked 0.6 more miles than Elena.
Step-by-step explanation:
First we multiply both 3 and 2.8 by 3 to represent how far each of them will walk in 3 hours
Jada: [tex]3*3=9[/tex] miles
Elena: [tex]2.8*3=8.4[/tex]
Now we subtract the two numbers to see how much further Jada walked
[tex]9-8.4=0.6[/tex]
Jada walked 0.6 more miles than Elena in 3 hours.
I hope this helps
