Hi. This is just another method you can use. Purely, numerical calculation. Algebra not required. However, if you are more familiar with algebra and prefer it, I suggest you to go with the solution given by another tutor. You may use my method as a reference. Thanks. :)

If you're asking how I get 41/9 h as the total time, I divided the the distances by their speed at each points and adding them up. This gives me 41/9 h. Finally, I divide total distance by total time to get the average speed.
