106. According to numerous websites, the average American drinks the equivalent of 5.97 X 10^2 cans of soda per year. According to the U.S. Census Bureau, the population of the United States at the end of 2008 was about 3.06 X 10^8. How many cans of soda were consumed in the United States at the end of 2008? Write your answer in both scientific and decimal notation, then write how the decimal answer would be read aloud. 107. The speed of sound in air is about 1.126 X 10^3 feet per second. When the volcano Krakatoa erupted on August 26, 1883, the blast could be heard 3,000 miles away. How long would it have taken for the sound to reach that far?Explanation / Answer
1.) NUMBER OF CANS THE AVERAGE AMERICAN DRINKS PER YEAR = 5.97 * 10^2
THE POPULATION IN THE YEAR 2008 IN U.S. = 3.06 * 10^8
THE NUMBER OF CANS THAT WERE CONSUMED BY U.S . CITIZENS IN THE YEAR 2008 IS = 5.97*10^2 * 3.06 * 10^8 = 1.8262 * 10^11 SCIENTIFIC NOTATION .
1,82,62,00,00,000 DECIMAL NOATION OR EIGHTEEN THOUSAND TWO HUNDRED SIXTY TWO MILLION IN WORDS.
2.) SPEED = DISTANCE/TIME.
TIME=DISTANCE/SPEED
1 FOOT = 0.000189394 MILES
SPEED GIVEN= 1.126*10^3 FOOT / SEC = 1126 FOOT / SEC = 0.000189394 * 1126=0.2132576 MILES / SECOND .
DISTANCE GIVEN = 3000MILES
TIME=DISTANCE/SPEED = 3000/0.2132576 SECONDS =14067.49 SECONDS OR
1 HOUR =3600 SEC = 60 MIN
? HOUR = 14067.49 SEC
14067.49/3600 = 3.9 HOURS = (14067.49*60)/3600 = 234.45 MINUTES .
