pls help me, thanks

My workout was this on the treadmill

5 min warm up.. 4 mph
25 min at 5.5 mph
5 min at 3.5 mph
25 min at 5.5 mph
and then 3 min at 3.5 mph and that's it
total time for this workout is 1 hour and 3 mins.

so my new workout is this

5 min warm up.. 4mph
30 secs at 8 mph and 30 secs at 5 mph, back and forth for a total of 15 mins.
3 min at 4 mph
total time for this workout is 23 mins.

So I was wondering which workout would burn more calories.. thanks if you have the answer

Workout2 Fat-fighter combo
Warm up for five minutes at an easy pace, working up to a level 5. Bump it up to level 7 for the next three minutes; your sentences should start to get choppy. Return to an I-can-sing level-4 pace for a minute and a half. That's one set. Alternate until you've done five faster/slower sets (about 22 minutes). Continue at your easy level-4 pace for two and a half more minutes to cool down.

Make it harder: Extend your faster intervals and reduce the slower ones by 30 seconds each week.
Make it easier: Make both intervals two minutes each, extending the final slower one to four minutes
