Final answer:
To calculate the distance apart between you and your friend, use the Pythagorean Theorem. The distance is 5 blocks.
Step-by-step explanation:
To find the distance apart between you and your friend, we can use the Pythagorean Theorem.
First, let's represent your distance as one leg of a right triangle. You rode 4 blocks north, so this is the height of the triangle.
Your friend rode 3 blocks west, so this is the base of the triangle.
Using the Pythagorean Theorem, we can calculate the distance apart as follows:
distance apart =

distance apart =

distance apart =

distance apart = 5 blocks
