3600*3/45=10800/45=240

3 hours are 3600 seconds by 3 devide by time for 1 rotation (45 seconds) if it turns constantly without any stops

ok so 45 secs x 4 = 3 mins so in 3 mins there are 4 rotations
3 hrs = 180 mins
180/3=60 60*4=240
240 rotations

3 hours * 60 minutes * 60 seconds = 10,800 seconds (number of seconds in 3 hours)

10,800 / 45 seconds (1 rotation) = 240 rotations in 3 hours
