Since the gears are connected by a chain, they have the same LINEAR velocity:

 

r 15pi / 2    /60       =   27 pi/10

r =   27 pi/10  * 60 * 2/(15pi)   INCHES =   21.6 INCHES = 1.8 ft

 

Be careful......  everything has to be in seconds     or everything has to be in minutes  to get proper answer

  I converted   15pi/2  rad/min to   rad/sec by dividing by 60
