- Walch Education
Suppose two brothers who live 55 miles apart decide to have lunch together. To prevent either brother from driving the entire distance, they agree to leave their homes at the same time, drive toward each other, and meet somewhere along the route. The older brother drives cautiously at an average speed of 60 miles per hour. The younger brother drives faster, at an average speed of 70 mph. How long will it take the brothers to meet each other?
- Read and reread the statement carefully.
- Create expressions and inequalities from the known quantities and variable(s).
- Solve the problem for the time it will take for the brothers to meet each other.
