Imagine that you take a road trip from A to D, but you have to do it in segments. Let’s say the distance from A to B is 145 miles; from B to C is 160 miles, and C to D is 115 miles. It takes you 6 hours to drive from A to D. What was your average speed (in miles per hour) during your trip from A to D? (Hint: How many miles did you drive from A to D? Then divide the total miles by the number of hours).
