Ok, so I’m pretty sure that would be a little less than 7 minutes because if 5 min is -150 degrees then 1 min is around 25 degrees. So around 7 min would be the answer.
I believe the answer is 6000 millimeters. I am sorry if this answer is wrong. But I think it may be 6000 or close to it. Again I am super sorry if it is wrong. Have a nice day!!
