A flare is launched from the deck of a lifeboat 4 ft above the water surface. The initial upward velocity is 80 ft/s. After how many seconds will the flare be 100 ft above the water surface?

Answer: 1 24/80 of a second

Explanation:

Well so if you are at 4 ft after 1 second you need 16/80 of a second to reach 100 feet above because 80 then plus 16 plus the addition 4 ft that you are above the water would be 100 feet.
