Jacob walks 1.5 miles north.
He turns and walks 0.8 miles west.
We need to find how far is he from his starting point. Let he is at a distance of x miles from the starting point. It can be calculated as follows :
![x=\sqrt{1.5^2+0.8^2} \\\\x=1.7\ \text{miles}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B1.5%5E2%2B0.8%5E2%7D%20%5C%5C%5C%5Cx%3D1.7%5C%20%5Ctext%7Bmiles%7D)
Hence, he is 1.7 miles from his starting point.
