Answer:
[tex]d = 100-25t[/tex]
Step-by-step explanation:
Let's use basic logic here.
If we are 100 miles away from a place, and we've got 25 miles to go, we've already travelled 75 miles.
Since we've travelled 75 miles in 3 hours, then we travel at a rate of [tex]75\div3=25[/tex] miles per hour.
The distance to City A will be represented as 100 - miles already travelled. We can find how many miles have been travelled by multiplying 25 by [tex]t[/tex], the amount of hours we've spent driving.
This creates the equation [tex]d = 100 - 25t[/tex]
Hope this helped!
