Answer:
It would be the first equation that has a higher initial start. (d = -50t + 70)
Step-by-step explanation:
This is because 70 is greater than 65. Assuming that the 65 is the distance, we can say that the first equation has a higher initial start, that of 70 miles from destination, while the second equation starts from 65 miles from destination.
The negative for the 50 and 60 is counting down the amount of miles until the destination is reached.
