Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn’t so smart either. But now is not the time for regrets because you need to get away from these mutant zombies…fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how.
Lateral Thinking

Train A and train B are crossing the country, from coast to coast, over 3,000 km of rail road track. Train A is going from east to west at 80 km per hour, and Train B is going from west to east at 90 km per hour. Which train will be closer to the west coast when they meet? (Hint: You don't have to do any maths to get the answer. Just use your head!)
When the trains meet, they will be at exactly the same point. Therefore, they will each be the same distance from the west coast.
How much dirt is in a round hole that is 9 feet deep with a diameter of 3 feet? (Hint: You don?t have to do any math to get the answer. Just use your head!)
None. You make a hole by digging out the dirt, so the hole is empty.

The rope ladder of a boat hangs over the side of the boat and just reaches the water. Its rungs are 8 inches apart. How many rungs will be under the water when the tide rises 4 feet?
When the tide rises 4 feet, the boat and its ladder will also rise. So no rungs will be under the water.
