Answer:
The total distance in miles at x = 2 hours will be 543.2 miles.
Step-by-step explanation:
Given
Given the linear model function
y = -67.9x +679
where
y represents the distance, in miles y, is a function of time, x, in hours
To determine:
Use the model to calculate the total distance, in miles, at x = 2 hours
substituting x = 2 in the function
y = -67.9x +679
y = -67.9(2) +679
y = -135.8 + 679
y = 543.2 miles
Therefore, the total distance in miles at x = 2 hours will be 543.2 miles.
