Question 18
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 from Davao city to Agora, Cagayan de Oro. Then, a ferry boat running at 26.67 km/hr from this port to Cebu would take 9 hours. If the average speed of the total trip is 36 km/hr, what is the speed during the land travel?
