Answer:
First convert the minutes in seconds
Step-by-step explanation:
3 minutes 20 seconds =3×60=180+20=200 seconds
3 minutes 40 seconds =3×60=180+40=220 seconds
4 minutes =4×60=240 seconds
Then find LCM of : 200,220,240= 13200 seconds
Now convert 13200 seconds into minutes =13200÷60= 220 minutes
Now convert 220 minutes into hours =220÷60 =
Quotient =3
Remainder =40
= 3:40 p.m.
