Time calculation by adding minutes

[lavan_joy]

Hi Excel experts

I need some formulas for the following:
Example:
Start time: 10:30 + 75 minutes = End Time1+ 90 minutes =End Time 2+60 minutes =End Time 3

Start time- Manual Entry
Minutes- Manual Entry
End Time1,End Time 2, End Time3… should be calculated

I have attached the sample excel sheet.
