Two cars leave the same place at the same time. One car drives northwest at mi/h and the other car drives southwest at mi/h. How many miles apart are the cars after Determine path geometry: Northwest and Southwest directions are 90 raised to the composed with power apart, forming a right triangle. Calculate individual distances: In 30 minutes ( Car 1 travels: Car 2 travels: Apply Pythagorean theorem: Simplify calculation: Scale by 2 to use whole numbers ( ). This is a multiple of the Scale back down by 2: Problem 3: Probability and Combinatorics Since its founding in 1983, this round has
