Answer: White House tours are scheduled on a first come, first served basis and they must be requested a minimum of 21 days in advance of your visit. Requests can be submitted up to three months in advance. The earlier, the better as only a limited number of spaces are available.
Step-by-step explanation: u need to tour to get in
Start with 21 cups , substract 5.5 (5 and one half) , 2.25( 2 and one fourth), and then divide by two (divided into 2 equal portions) and the result is 6.625 and if you divide the options as an improper fraction, you'll get 6 and five eights... so your answer is D.
1 mile = 5280 feet
81 * 5280 = 427680 feet per hour
1 hour = 3600 seconds
427680 / 3600 = 118.8 feet per second
118.8 * 15 = 1782 feet in 15 seconds
