Emma’s average speed in kph should be 54 kilometers per hour. I got this by putting 1 hour and 20 minutes into just minutes. which would be 80 minutes then dividing 72km by 80 minutes. Which gave me 0.9. Then multiplying 0.9 by 60 because there are 60 minutes in an hour. Which gave me 54 kph. hope I helped.
