A diver descends at a rate of 12 feet per minute. At this rate, where will the diver be in relation to the surface after 4 minutes?
A. -48 ft.
B. 58 ft.
C. -16 ft.
D. 3 ft.
The rate of change is given as 12 feet per minute. This can be represented as -12t, where t represents time, in minutes. Plug in 4 to -12t for t and you get -12 x 4 = -48.
