1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.
The measure of an obtuse angle is greater than 90 degrees and less than 180 degrees.
The stalactites become 0.004 + 0.006 = 0.01 inches closer each year, and begin 10 feet apart, or 120 inches apart.
let y be the distance between them, and x be the number of years that go by:
y = -0.01x + 120
We want to find where y = 0, where they meet:
0 = -0.01x + 120 Add 0.01x to both sides
0.01x = 120 Multiply both sides by 100
x = 12,000
The stalagmite and stalactite will meet in 12,000 years
