Joseph traveled from Boston to Framingham at 50 mph and then back to Boston at 40 mph. What was Joseph's average speed on the round trip?

Joseph's average speed on the round trip is 45 mph

Average speed is the the ratio of the total distance travelled to the total time taken to cover that distance. Average speed is given by the equation:

Average speed = Total distance / total time taken

The SI unit of average speed is the meters per second.

Also when given two or more speeds, the average speed can be gotten by taken the average of the two speeds.

Given that Joseph traveled from Boston to Framingham at 50 mph and then back to Boston  at 40 mph, hence:

Average speed = (50 mph + 40 mph) / 2 = 45 mph

Hence the average speed is 45 mph

in conclusion, "ppl are so gay" due to their genetics.
