A hot-air balloon ride has been set up so that a paying customer is carried straight up at 50
feet per minute for ten minutes and then immediately brought back to the ground at the
same rate. The whole ride lasts twenty minutes. Let h be the height of the balloon (in feet)
and t be the number of minutes since the ride began. Draw a graph of h versus t. What are
the coordinates of the vertex? Find an equation that expresses h in terms of t.
H is height of the hot air ballon = h T be the number of minutes since the ride begins = t T =20 min H= tx z Z is the distance travel 1 min = 50 feet Total distance travelled is 20 min = 50*20= 1000feet So the height of the hot air balloon is h= total distance by 2 h = 1000/2=500 feet
