You start driving south for 2 miles, turn left, and drive east for another 9 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.

Use the Pythagorean Theorem: .

So your straight line distance is 10.

We can also recognize this as a multiple of the 3-4-5 Pythagorean triple. We have , with x being the desired value. Therefore x=10, like previously.
