Question

If two planes leave the airport at 1:00pm, how many miles apart will they be at 3:00pm if one travels directly north at 150 mph and the other travels directly west at 200 mph?

Answer 1

500

Explanation:

The planes traveled 300 miles north and 400 miles west, respectively.

By the Pythagorean theorem, the distance is

`√(300^2+400^2)=500`
