Question

You start driving west for 3 miles, turn right, and drive north for another 13 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.

Answer 1

13.3 miles to nearest 1/10.

Explanation:

The journey forms a right triangle so by Pythagoras:

d^2 = 3^2 + 13^2

d^2 = 9 + 169

d^2 = 178

d = 13.34 miles.
