Final answer:
The equation for the time it takes Andre to travel a distance of d miles is Time = 68 miles / Speed.
Step-by-step explanation:
To write an equation for the time it takes for Andre to travel a distance of d miles, we can use the formula:
Time = Distance / Speed
Since Andre drives at the same speed, we can substitute the given value of 68 miles for distance to get:
Time = 68 miles / Speed
This equation represents the relationship between the time it takes Andre to travel a distance of d miles and the speed at which he drives.
