Now if we subtract 1 hour to minutes won't it become 75 and you told that 1 hour =60 minutes . why is it becoming more???????
Dear Student!
Your question is not clear. Recheck your question and do get back to us so that I could provide you meaningful help.
15 minutes + 1 hour = 15 minutes + 60 minutes = 75 minutes
135 minutes – 1 hour = 135 minutes – 60 minutes = 75 minutes
Cheers!
