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.
