Question

The 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. What distance will it take you to stop while talking on a cell phone if you are driving 30 mph? Round your answer to the nearest hundredth.

a) 0.25 feet
b) 0.37 feet
c) 0.50 feet
d) 0.75 feet

Answer 1

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.
