Question 17
Aside from the capital Manila, two other major cities in the Philippines are Cebu and Davao. It is possible to travel between these two cities by a combination of land and sea travel. One may take a 6-hour bus running at 50 km/hr from Davao city to Agora, Cagayan de Oro. Then, a ferry boat running at 27.8 km/hr from this port to Cebu would take 9 hours. What is the average speed of this trip from Davao to Cebu?
