Arrival: 5:06 P.M. EST
Travel Time: ?

Answer 1

arrival - departure

Answer 2

@aaronq So i have to subtract the time arrived from the time Departed or wouldn't it be the other way around?

Answer 3

because what Im wondering is I have the answer and it is 7hr. 41min. but I'm not quite sure about the process of how to get that..

Answer 4

you're finding the difference, in which time has elapsed.

If you were to do it your way, you would end up with a negative number, and you can't have negative time, can you?

Answer 5

The diference would be 4hrs and some mins wouldnt it?

Answer 6

you're not taking the PM and AM into account..

convert it to the 24 system and you'll see what i mean

Answer 7

I'm not surek.. I will have to try to research more. sry

Answer 8

okay, so,

Departure: 9:25 A.M. EST ... in 24 hour system .. 9:25
Arrival: 5:06 P.M. EST .. in 24 hour system ... 17:06

does that sound better?

Answer 9

How did you convert 5:06 to 17:06?
I know im missing something ive learned

Answer 10

well 5 PM is 5 hours past noon...

so 12 + 5:06 = 17:06

Answer 11

so anything you have in PM just add 12 hours to it, then you have it in the 24 hour system

Answer 12

oh ok I see!! and if I had one like this..
Departure: 1:10 P.M. EST
Arrival: 8:29 P.M. PST

Answer 13

since they're both in PM you don't need to change it, if you add 12 to both the 12 will just cancel out

Answer 14

ok thank you. :)

Answer 15
