Coach had the entire track team run 4 laps. When they finished, he had the distance runners run some more laps. Each distance runner ran 40 laps in all. Use an algebraic equation to find how many laps the distance runners ran after the rest of the team had finished running?
ANSWER:
laps run with the team + more laps run = laps run in all
4 + r = 40
Subtract 4 from each side of the equation to get the variable, r, by itself. Then do the operations.
4 + r = 404 - 4 + r = 40 - 4
r = 36
The distance runners ran 36 more laps after the rest of the team had finished running.
