Final answer:
The average number of miles you should plan to cover each day on a long trip depends on various factors, such as the distance of the trip and the mode of transportation.
Step-by-step explanation:
The average number of miles you should plan to cover each day on a long trip depends on various factors, such as the distance of the trip and the mode of transportation. However, as an example, let's consider the average daily mileage for a long road trip.
According to the given reference, we can calculate the average daily mileage by dividing the total distance traveled by the number of days.
For example, if you plan to cover 1,000 miles in 5 days, the average daily mileage would be 1,000 / 5 = 200 miles per day.
