Starting at home, emily traveled uphill to the hardware store for 60 minutes at just 6 mph. she then traveled back home along the same path downhill at a speed of 12 mph. what is her average speed for the entire trip from home to the hardware store and back? (i need the rate version for this. 24 and 6 are not correct)
