Answer:

240

Step-by-step explanation:

If you are going 120 mph for 2 hours. You simply multiply the two values, giving 240 and the units for this is miles because in the multiplication, the units are m/h * h and this cancels out the hours and leaves just miles.

Answer: Choice D
z = 13/3 or z = -11/3

------------------------------------

Work Shown:

|z - 1/3| = 4
z - 1/3 = 4 or z - 1/3 = -4
using the rule that if |z| = k, then z = k or z = -k for some positive number k

Solve z - 1/3 = 4 to get...
z - 1/3 = 4
z - 1/3+1/3 = 4+1/3
z = 4+1/3
z = 12/3+1/3
z = (12+1)/3
z = 13/3

Solve z - 1/3 = -4 to get...
z - 1/3 = -4
z - 1/3+1/3 = -4+1/3
z = -4+1/3
z = -12/3+1/3
z = (-12+1)/3
z = -11/3
