Question 496860: Two cars, 360 kilometers apart begin driving toward each other on a long straight highway. One car travels 80 kilometers per hour and the other 100 kilometers per hour. At the same time a canary, starting on one car, flies back and fourth between the two cars as they approach each other. If the canary flies 120 kilometers per hour and spends no time to turn around at each car, how far has it flown when the cars collide?

Two cars, 360 kilometers apart begin driving toward each other on a long straight highway. One car travels 80 kilometers per hour and the other 100 kilometers per hour. At the same time a canary, starting on one car, flies back and fourth between the two cars as they approach each other. If the canary flies 120 kilometers per hour and spends no time to turn around at each car, how far has it flown when the cars collide?
-------------------
The cars are going in opposite directions so their speeds are added.
80 + 100 = 180 km/hr
They start 360 km apart, so it takes them 360/180 = 2 hours to meet.
-----------
The bird flies 120 km/hr for 2 hours = 240 km
