Has to multiply I think try that !
Answer: 37
Step-by-step explanation:
a=12
35 < b < 40

31.288889,because hours have 60 min,1 min have 60 seconds so you will do 64/60=1.066666667/60=.0177777778

I have drawn a diagram
The green is the angle bisectors and the yellow the perpendicular bisectors.
You can see the problem straight away
