yarga [219]

Answer:

  26 2/3 mph

Step-by-step explanation:

  time = distance/speed

  speed = distance/time

Use the first of these relations to find Aidan's time getting to school:

  time = 16 mi/(40 mi/h) = 16/40 h = 0.4 h

Then the time Aidan takes to get home is 0.6 hours, and his average speed for that trip home is ...

  speed = 16 mi/(0.6 h) = 26 2/3 mi/h
