Question

You start driving west for 3 miles, turn right, and drive north fer 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

For this problem, the best way to solve is to use the Pythagorean theorem: a^2 + b^2 = c^2

3^2 + 13^2 = c^2
C = sqrt of 178, or 12.3

Hope this helps!

Answer 2

13.3 miles

Explanation:

So you're driving <----- for 3 miles

Then you start driving up for 13 miles

This makes a right triangle with sides of 3 and 13

using pathagoreas, a^2+b^2=c^2

3^2+13^2=c^2

9+169=c^2

178=c^2

Square root both sides

c= 13.3416640641

Rounding, it's 13.3 miles
