Help 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 thi?

Answer 1

(120+124+#MILESFROM3RDRACE#)/3 = 123

so

120+124+#MILESFROM3RDRACE# = 123 * 3

it follows that

#MILESFROM3RDRACE# = (123 * 3) - 120 -124

You can do the math since the equation is worked out.

Answer 2

125
