Quizplus · Accepted Answer

Distance traveled = velocity x time. 
Here, the object is traveling at a constant velocity of 20 feet per second and the time given is 16 seconds. 
Using precalculus, distance traveled = 20 x 16 = 320 feet. Distance traveled is equal to velocity multiplied by time, which is a basic precalculus concept. Therefore, solving the problem only requires multiplication: 
distance traveled = 20 ft/s x 16 s = 320 ft.
