The flight time from houston to london is 9 hours 40 minutes. if i arrive at 4: 30,what time did i set off ?

6:50 a.m. or 6:50 p.m.

Step-by-step explanation:

We are given;

We are required to determine the set off time

12 hours + 4:30 = 16: 30

Thus, set off time = 16:30 - 9 hrs 40 minutes

                            = 6:50 a.m.

Set off time = 0430 hrs - 9 hours 40 minutes

                   = 6:50 p.m

Therefore, the set of time is 6:50 a.m. or 6:50 p.m.
