A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mile. The boat is launched from the point (−6, 0) and goes to point (−6, −6) to fish. From there, the boat travels to (0, 0) to fish and then goes back to the launch point.

Determine the total number of miles traveled. Round to the nearest whole number.

a 72 miles
b 20 miles
c 8 miles
d 6 miles

The distance between the launch point (-6, 0) and the fishing point (-6, -6) is 6 units (6 miles), because (-6, -6) is 6 units below (-6, 0).

The distance between the fishing point (-6, -6) and the fishing point (0, 0) is also 6 units (6 miles), because (0, 0) is also 6 units away from (-6, -6).

The distance between the fishing point (0, 0) and the launch point (-6, 0) is 6 units (6 miles), because (-6, 0) is 6 units away from (0, 0).

Therefore, the total distance traveled is 6 miles + 6 miles + 6 miles = 18 miles.

Rounding to the nearest whole number, the total distance traveled is approximately 18 miles.

As such, the correct answer is not provided.
