Back to Business

In 1870, which Salt Lake City Building received Utah’s first air conditioning?
a.                   The Salt Lake Temple
b.                  The Salt Palace
c.                   The Salt Lake Tabernacle
d.                  The State Building
Yesterday’s answer:
(D)   221 million miles
According to the United Nations Children’s Fund (UNICEF), there are 2,106 million children under age 18 in the world. If there are on average 2.5 children per household, Santa would have to make 842 million stops on Christmas Eve, traveling 221 million miles. To reach all 842 million stops, Santa would need to travel between houses in 2/10,000 second, which means he would need to accelerate 12.19 million miles (20.5 billion meters) per second on each stop. The force of this acceleration would reduce Santa to “chunky salsa.”
