A hot-air balloon is ascending at the rate of 75 km/h and is 200 ft above the ground when a package is dropped over the side. How long does the package take to reach the ground? With what speed does it hit the ground?

Step 1
Since 1 km = 3280.84 ft and 1 hour = 3600 seconds, we can calculate: 75 km/h * 3280.84 ft/km * 1 hour/3600 seconds = 82.02 ft/s So, the hot-air balloon is ascending at a speed of 82.02 ft/s. Show more…
