10. Kyle and Jenna walk to the same school from their houses in the morning. Kyle lives 450 meters from the school and travels at an average rate of 30 meters per minute. Jenna lives 400 meters from school and travels at an average rate of 25 meters per minute. If they both walk directly to school, leaving home at the same time, who will arrive first? How soon after the first person will the second person arrive?

What if... ...this problem was more realistic? Re-write the problem and solve your new problem (or estimate). ...Kyle and Jenna have a friend who lives 1500 meters from school and bikes at an average rate of 90 meters per minute? ...Kyle and Jenna were riding their bikes? How fast might they be going?
