You can put this solution on YOUR website! let them meet after x+180
The time taken by dog to travel 180+x = time taken by rabbit to go x meters
time = distance / speed
x+180 / 9= x/5
4x+900=9x
9x-5x=900
x=900 /4
225
225+180= 405 meters

----------------------
The dog gains on the rabbit at 4 meters/unit time (whatever the units are)
180/4 = 45 units
9*45 = 405 meters
