D = r * t
D = 65 * 7/3 = 151 2/3
151 2/3 = 65t
151 2/3 = 43t
Compare the two.
You normally drive the south expressway between Calubang and Magallanes at an average velocity of
105km/hr (65mi/hr), and the trip takes 2 hours and 20 minutes. On a Monday morning, however,
heavy traffic slows you down and you drive the same distance at an average velocity of only 70km/hr (43mi/hr).
How much longer does the trip takes?
