Travel Graphs and Average Speed

In this video tutorial, Raphael Thompson guides grade 7-9 students through understanding travel graphs using Ray's trip to the mall as an example. The lesson covers calculating distances, times, and average speeds, as well as identifying key moments during the trip, such as arrival and rest stops. Students are encouraged to find answers on the graph and verify them with provided solutions.
