A truck enters a stretch of road that drops 4 meters in elevation for every 100 meters along the
length of the road. The road is at 1,300 meters elevation where the truck entered, and the truck
is traveling at 16 meters per second along the road. What is the elevation of the road, in
meters, at the point where the truck passes t seconds after entering the road? - Correct
Answers-1,300 − 0.64t
