Four people need to cross a rickety bridge at night, but they must use a single flashlight to see where they’re going. The bridge can only hold two people at a time, and both must move at the speed of the slower person. The flashlight must always be carried across the bridge, meaning someone must bring it back for the next group.
Each person takes a different time to cross:
How can all four people cross the bridge in just 17 minutes?
2 + 1 + 10 + 2 + 2 = 17 minutes
Two trains are 50 miles apart, traveling toward each other at 25 miles per hour each. A bird starts flying from the front of one train at 100 miles per hour, flying back and forth between the two trains until they collide. How far does the bird travel before the collision?

Instead of calculating each individual leg of the bird’s flight, let’s take a simpler approach using time.
Time until collision:
Distance traveled by the bird:
