Four runners are training for long races. Noah ran 5.123 miles, Andre ran 6.34 miles, Jada ran 7.1 miles, and Diego ran 8 miles.

kkurt [141]

Answer:

Jada ran 1.977 miles farther than Noah.

Step-by-step explanation:

Jada = 7.1m [J=7.1] & Noah = 5.123m [N=5.123] & Additional miles = AM

J-A=AM

7.1-5.123=AM

7-5=2, 0.1-0.123=-0.023

2-0.023=1.977

AM=1.977
