Well in football, each quarter is 15 minutes long so you could have 2 quarters in 30 minutes.
Divide "9 hours 35 min" by 1.
It is 35 min past 8.
It is 35 min to 10.
8 hrs 35 min
2100 of them.
35 X 60 = 2100 sec.
5 hrs 41 min
35 minutes.
The answer will depend on how quickly it heats up to 35 deg, but it should be 3 times.
There are 60 sec in one min 35 rev/min x 45/60 = 26.25 revs
3 hours = 3*60 = 180 minutes. So, 35 min, as a frcation of 3 hours = 35/180 = 7/36 or 19.44... %
