Anthony is in a hot air balloon over the ocean at a height of 4 feet.
He drops his full Pepsi can into the water and it lands in shallow water 3 feet below the surface.
How many feet did that Pepsi can travel?
He is 4 feet up so that Pepsi goes 4 feet to the surface, and then ANOTHER 3 feet to the bottom.
4 + 3 = 7
