Final answer:
The travel distance to an exit must not be more than the actual distance needed to reach the exit.
Step-by-step explanation:
In physics, when referring to the travel distance or total travel distance to an exit, it is important to ensure that it is not more than the actual distance one needs to travel to reach the exit. This is because exceeding the actual travel distance can result in inefficiency, wasted time, or even a failure to reach the exit. For example, in a round trip to the store, the total distance traveled is 6 km. The distance to the store and back should not exceed this total distance.
