Answer

Explanation:

Step1: Convert mph to feet - per - second

1 mile = 5280 feet, 1 hour = 3600 seconds. So 55 mph = 55×5280÷3600 $\approx$ 80.67 feet - per - second. But we don't actually need to convert the speed precisely for a rough estimate. A common rule - of - thumb for passing at highway speeds: A safe passing time is around 10 seconds.

Answer:

10 seconds
