Question: Suppose that after a hike in the mountains, a friend asks how fast you walked. You recall that the trail is about 6 miles long and that it took between two and three hours.

Part A: What is your average speed if you assume the average time of 2.5h?

I've already tried my hand at this a few times and the system says my answer differs significantly from what is required. Can you please try to be a little thorough in your explanation or maybe show additional working out?
