Here is today's Problem of the Day, brought to you from MathMastery Daily Brains:
Solar Eclipse A solar eclipse occurs when the moon moves between the sun and the earth and casts a shadow over part of the earth. It is called a total solar eclipse when the moon's shadow completely blocks out the sun. During a total eclipse, you can see a ring of gas around the sun. The ring of gas is referred to as a halo and is called the corona.
The first total solar eclipse of the decade took place on June 21, 2001. It was visible over the Atlantic Ocean, Africa and Madagascar. The next total solar eclipse took place in 2002 and the closest one after that will be in 2017. The total solar eclipse that took place in 2002 was on December 4 and was visible in southern Africa, over the Indian Ocean, and in Australia. The eclipse that takes place on August 21, 2017 will be visible from Oregon to South Carolina. (We might get to see it here in Bellingham!)
Exactly how much time (years/months/days) will there be between the two total solar eclipses in 2002 and 2017? Answer in the Comments section of today's posting. Be sure to explain how you got your answer.
