Question 247360: A truck traveling at a constant rate of 45 miles per hour leaves Albany. one hour later a car traveling at a constant rate of 60 miles per hour also leaves albany traveling in the same direction on the same highway. how long will it take for the car to catch up to the truck, if both vehicles continue in the same direction on the highway? Answer by solver91311(24713) (Show Source):
Do this in your head. An hour after the first guy leaves going 45 miles per hour, he is 45 miles down the road. The other guy is going 15 miles per hour faster, so how long would it take someone going 15 miles per hour to go 45 miles? Think about it this way, what if the car stopped completely after an hour and the truck was only going 15 mph? Same as the car continuing at 45 and the truck going 60 -- the truck would catch up at a different place, but the amount of time would be the same.
