jada walks at a speed of 3 miles per hour. elena walks at a speed of 2.8 miles per hour.
We find the distance both walked in 3 hours
distance = speed * time
Distance Jada walks = 3 * 3 = 9 miles
Distance Elena walks = 2.8 * 3= 8.4 miles
Now we find the difference of distance walked
Jada's distance - Elen's distance
9 - 8.4 = 0.6
jada walks 0.6 miles farther after 3 hours
