"A certain automobile manufacturer claims that their deluxe sportscar will accelerate uniformly from rest to 87 miles per hour (mph) in 8 seconds. Determine the acceleration of the car, and find the distance traveled in 8 seconds. Leave your answer in miles and hours."

If it accelerates uniformly then the average speed during the first 8 seconds would be 43.5 mph, i.e.0.725 miles per minute.or in other words 0.012 miles per second. Given that it had 8 seconds to move then it would have traveled 0.09667 miles or 154.87 mtrs (1 mile is approx. 1600 mtrs.).

wouldn't you need to convert the 8 seconds into hours then you use the position function and it's first derivative? plug the values back into postion function to get distance?
hope this helps.
