Answer:
2. Speed of the car.
Step-by-step explanation:
Given equation:
[tex]D=280-59t[/tex]
where:
The car begins its journey at Albany.
Therefore, the car is at Albany when t = 0:
[tex]t=0 \implies D=280-59(0)=280[/tex]
Therefore, 280 represents the distance between Buffalo and Albany.
After 1 hour of driving:
[tex]t=1 \implies D=280-59(1)=221[/tex]
Therefore, after 1 hour of driving, the car is 59 miles closer to Buffalo and therefore 59 miles from Albany.
After 2 hours of driving:
[tex]t=2 \implies D=280-59(2)=162[/tex]
Therefore, after 2 hours of driving, the car is 158 miles closer to Buffalo and therefore 158 miles from Albany.
Therefore, the 59 represents the speed of the car as the car travels 59 miles per hour.
