Answer: 8:30am/pm time
Explanation:
7:40am/pm time + 50 minutes
7:40am/pm time after 10 minutes = 7:50am/pm time | 7:40am/pm time + 10 minutes = 7:50am/pm time
7:40am/pm time after 20 minutes = 8:00am/pm time | 7:40am/pm time + 20 minutes = 8:00am/pm time
EX: Because after :59 minutes/seconds you increase the hour or minute by 1 which then would be 1:00 hour/minute
7:40am/pm time after 30 minutes = 8:10am/pm time | 7:40am/pm time + 30 minutes = 8:10am/pm time
7:40am/pm time after 40 minutes = 8:20am/pm time | 7:40am/pm time + 40 minutes = 8:20am/pm time
7:40am/pm time after 50 minutes = 8:30am/pm time | 7:40am/pm time + 50 minutes = 8:30am/pm time
