Final answer:
The time it takes for a typical tractor-trailer to cross a track depends on the distance covered before hitting the brakes, the stopping time, and the total stopping distance.
Step-by-step explanation:
The time it takes for a typical tractor-trailer to cross a track depends on several factors:
- The distance the driver covers before hitting the brakes.
- How long it takes the truck to stop after hitting the brakes.
- The total distance the truck covers to stop.
To calculate the time it takes for the truck to cross the track, we need to know these distances and times. Once we have this information, we can use the formula time = distance / speed to compute the time taken.
