Timmy's birthday is 53 days away. Which of these is greater than 53 days?

I would suggest you convert each of the answers into days. For example,
3 weeks x (7 days/1 week) = 21 days
etc.
For B, there are 24 hours in 1 day
For C, there are about 30 days in a month
For D, there are 24 hours in 1 day.
But I assume you know all of those conversion factors.

240 hours
