I went about trying to determine a sum formula for the fly's distance traveled but could not get very far. Any help available would be appreciated. Thanks in advance.

Hi,

I wasn't sure how to even start approaching the problem (determining the equation for the series).

How long until they meet? If the fly is flying at 7 m/s how far does it fly in that time?
