How many calories do you burn on a cross trainer on it's easiest setting for 45 minutes?

How many calories does a 17 year old, 6ft, 140 pound man burn on a cross trainer on it’s easiest setting for 45 minutes?

Thanks.

    without seeing the crosstrainer and checking the subject for resting heart rate i would wager to guess you’ll melt about 700 an hour.
