D. Because if one time is a certain amount of time away from 12pm and the other one is a certain amout away from 12pm then you add them up and get a number of hours and minutes
279ft/9sec = xft/1sec
Cross multiply to get
9x = 279 divide by 9
x = 31
31 feet per second
Seven units long. The distance between 2 sides, in this example is 6, and -1. The distance between 6 and -1 is 7, so when you add units, you get 7 units.
