Athletic race

Before a race, you start 4 5/8 feet behind your friend. You are 3 2/3 feet ahead of your friend at the halfway point. What is the change in distance between you and your friend from the beginning of the race?

Correct answer:

d =  8 724 = 199/24 ft

Step-by-step explanation:

a=332=3+32=33 3+2=39+2=3113.6667 ft b=485=837=4.625 ft  d=a+b=311+837=2488+24111=2488+111=24199=24199 ft=8247 ft=8.2917 ft
