Question

Julian jogs 222 kilometers east, 444 kilometers north, and then 777 kilometers west. how far is julian from his starting position, to the nearest tenth of a kilometer?

Answer 1

If you would like to know how far is Julian from his starting position, you can calculate this using the following steps:

First, you have to make a right triangle, where the hypotenuse of this triangle will actually be the distance we are looking for. The distances of the other two sides are 444 kilometers, and 777 kilometers - 222 kilometers; to be exact: 444 kilometers and 555 kilometers.

The distance we are interested in ... d:
d^2 = 444^2 + 555^2
d^2 = 197136 + 308025 = 505161
d = sqrt(505161)
d = 710.7 kilometers

The correct result would be 710.7 kilometers.
