Question

marvin is trying to get to his friend's house. he walks 4 blocks north to the park, then turns right and walks 3 blocks. finally he turns right and walks 4 blocks. how far from his starting point does he wind up?

Answer 1

Answer: Marvin walks a total of 4 + 3 + 4 = 11 blocks.

To find how far he is from his starting point, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the 4 blocks north and 3 blocks east form the legs of a right triangle, and the distance Marvin is from his starting point is the hypotenuse.

So we can calculate it as follows:

distance = sqrt(4^2 + 3^2) = sqrt(16 + 9) = sqrt(25) = 5

Therefore, Marvin is 5 blocks from his starting point.
