Hanna’s hot-air balloon is ascending at a rate of 15 ft/s. A wind is blowing continuously from west to east at 24 ft/s. Write parametric equations to model this situation, and decide whether or not the hot-air balloon will clear power lines that are 300 ft to the east and 95 ft tall. Find the time it takes for the balloon to reach or pass over the power lines.
