Plz hurry 30 pts for first one

Starting at home, Ishaan traveled uphill to the grocery store for 12 minutes at just 15 mph. He then traveled back home along the same path downhill at a speed of 30 mph. What is his average speed for the entire trip from home to the grocery store and back?

If the answer has to be in mph I would say 22.5. This is because the average of 30 and 15 is ([30+15]/2) 22.5.
