Explanation

Travel time = 2400 / 60 = 40 hours. Stops = 3 * 2 = 6 hours. Total time = 40 + 6 = 46 hours.

AI explanation

First calculate the driving time using the formula time equals distance divided by speed. The driving time is 2,400 miles divided by 60 miles per hour, which equals 40 hours. The train makes 3 stops of 2 hours each, adding 6 hours to the driving time. Adding these together gives a total journey time of 46 hours.
