Answer:
Not a direct variation
Step-by-step explanation:
• The distance to the camp = 200 miles
,
• The speed at which you are traveling = 50mph
The number of miles, n, that you have left to travel after t hours can be derived using the formula:

Substitute values of t from 1:

Observe that as the value of t increases, the number of miles, n decreases.
Thus, the relationship between n and t is NOT a direct variation.
