Question 107900
Ruth's car traveled 120 miles during the first race. During the second race, it traveled 124 miles. If the car averaged 123 miles over the first three races, how far did it travel during the third race?
----------------
The average of three numbers is the sum of the numbers divided by three.
--------------------
Let distance on the third race be "x" miles.
EQUATION:
(120+124+x)/3 = 123
244+x = 369
x = 125 miles
