9.Your mother takes you to your grandparents' house for dinner. She drives 60 minutes at a constant speed of 40 miles per hour. She reaches the highway, quickly speeds up, and drives for another 30 minutes at constant speed of 70 miles per hour. How far did you and your mother travel altogether?

How long did the trip take?

Your older brother drove to your grandparents' house in a different car but left from the same location at the same time. If he traveled at a constant speed of 60 miles per hour, explain why he would reach your grandparents' house first. Use words, diagrams. or numbers to explain your reasoning.
