# Write a program in Ruby that tells you how old I am
# if I am 979000000 seconds old.  Display the result as a floating point (decimal) number to two 
# decimal places (for example, 17.23). Note: To format the output to say 2 decimal
# places, we can use the Kernel's format method. For example, if x = 45.5678 then format("%.2f", x) 
# will return the string 45.57
