Final answer:

The average stopping distance on dry, level pavement when driving 55 mph is approximately 240.49 meters.

Step-by-step explanation:

The average stopping distance on dry, level pavement when driving at 55 mph can be calculated using the equation:

d = v2 / (2a)

where:
d is the stopping distance
v is the initial velocity (55 mph = 24.6 m/s)
a is the acceleration

On dry pavement, the coefficient of friction is typically around 0.7. Using this information, we can calculate the stopping distance:

d = (24.6)^2 / (2 x 0.7)

d ≈ 240.49 meters

Therefore, the average stopping distance on dry, level pavement when driving 55 mph is approximately 240.49 meters.
