The average speed of Jen for the entire journey is 30 mph.

Average speed

The average speed of a journey is the ratio of total distance to total time of motion.

Total time of motion = 3 + 9 = 12 hours

Total distance = 2[3(60)] = 2(180 miles) = 360 miles

Average speed = 360 /12

Average speed = 30 miles per hour

Thus, the average speed of Jen for the entire journey is 30 mph.
