A 2000 meter train leaves the train station traveling at a constant speed of 10 meters per second. A car parked at the back of the train leaves at the same time and after 100 seconds reaches the front of the train traveling at the same speed as the train. Let the f(t) = 10t be a model for the position in meters of the front of the train at t seconds. Write a function g(t) which is a model for the position in meters of the car at t seconds.

The sum of the angles in a triangle is 180°. this is called the angle-sum property.the sum of the lengths of any two sides of a triangle is greater than the length of the third side. similarly, the difference between the lengths of any two sides of a triangle is less than the length of the third side.the side opposite to the largest angle is the longest side of the triangle and the side opposite to the smallest angle is the shortest side of the triangle.
