Question

An air traffic controller has two jets on her radar. On a coordinate grid that is labeled in miles, the jets are located at (-20, 30) and (-20, -50). How far apart are the two jets?
120 miles


80 miles


40 miles


20 miles

Answer 1

Answer:

80 miles

Step-by-step explanation:

Note that the horizontal displacements of the jets are one and the same:  -20.

Thus, the distance between the jets is the difference between 30 and -50, which is 80 miles.

Answer 2

The are on the same line which makes it much easier.

We just have to find the distance between 30 and -50.

30-(-50) = 80 miles

answer: 80 miles
