Question

to get from your house to baseball practice, you have to drive 6 miles east and then 8 miles south. how much longer is the distance you have to drive compared to the straight line distance between your house and the baseball field?
the distance you have to drive is 2 miles longer.
the distance you have to drive is about 7 miles longer.
the distances are the same.
the distance you have to drive is 4 miles longer.

Explanation:

Step1: Calculate driving distance

$6 + 8 = 14$

Step2: Calculate straight-line distance

$\sqrt{6^2 + 8^2} = \sqrt{36 + 64} = \sqrt{100} = 10$

Step3: Find the difference

$14 - 10 = 4$

Answer:

The distance you have to drive is 4 miles longer.
