Ron lives in San Francisco and wonders if it would be faster to take the train or his car to work. The distance from his house to his office is 3 miles, and the train station is right next to his house. The car goes across town at an average speed of 10 miles per hour including stoplights and traffic. The train goes at an average speed of 65 miles per hour but has to make 5 stops each lasting 3 minutes. Which form of transit should he use if he wants to get to fast as fast as possible?
+36915 3 miles / 10 m/hr = .3 h for car = 18 minutes
3 m / 65 m/hr x 60 min/hr + 5 x 3 min = 17.78 min by train
