Question

3 hours 45 minutes+ 1 hour 35 minute​

Answer 1

Answer: 5.3 hours or 320 minutes

Step-by-step explanation: First convert all terms in minutes or hours (I am converting to minutes)

Formula is 1 hour = 60 minutes

3 hours = ? minutes

3*60 = 180 minutes

1*60 = 60 minutes

180+45+60+35

320 minutes

Now convert 320 minutes in hours (These step's is optional)

Formula is 60 minutes = 1 hour

320/60 = 5.3 hours
