Chad left his house to go on a road trip. He drove due north at 60 mph for the first two hours of the trip, and then drove due east at 50 mph for the next hour. After those three hours of driving, approximately how far was Chad from his house?

That is Correct: 130 miles.

Step-by-step explanation:

This is a right triangle problem. The pythagorean theorem states that a^2+b^2 = c^2 (hypotenuse)

One side of the triangle is 120 miles (60*2), the other is 50 (50*1).

120^2+50^2 = x^2

16900 = x^2

130 = x
