Final answer:
The stopping distance while talking on a cell phone at a speed of 30 mph is approximately 1.84 feet.
Step-by-step explanation:
The given function C = 0.00862 + LILA - 1.37 represents the stopping distance in feet while talking on a cell phone and driving at a speed of 1 mph. We need to find the distance it will take to stop while talking on a cell phone if the speed is 30 mph.
To find this distance, we can substitute the speed of 30 mph into the function and solve for C:
C = 0.00862 + LILA - 1.37
C = 0.00862 + (30 * 30) - 1.37
C = 1.8436
Therefore, the distance it will take to stop while talking on a cell phone at a speed of 30 mph is approximately 1.84 feet.
