It's Just Math

It's bike season! I can't wait to start riding. This makes me think of a math question.

Julian biked a 24 km trip to Edmonton. On his way there, his average speed was 12 km/h. On his way home, he stopped for a break, so his average speed was only 8 km/h.

What was his average speed, in km/h, for the entire round-trip?

You should ride your bikes to an ice cream shop and talk about how to do this question over a treat! It's not as straight-forward as it might first seem.
