Final answer:

The time it takes for a nerve impulse to travel from the foot to the brain over a distance of 2.02 m at a speed of 111 m/s is approximately 0.0182 seconds.

Step-by-step explanation:

When stepping onto a hot beach, the nerve impulse generated in your foot travels to your brain at a speed of 111 m/s covering a distance of 2.02 m. To calculate the time it takes for this impulse to reach the brain, we use the formula time = distance/speed.

Plugging in the values, we get time = 2.02 m / 111 m/s, which equals approximately 0.0182 seconds. Therefore, the correct option is a) 0.0182 seconds.
