No 1+1 does not equal fish.....I thought so too until I looked it up
Becky was trying to open the door, but it was stuck,
so she asked me to compound on it with her.
Change in altitude:
42,000 - 18,000 = 24,000 feet
Rate of change = 24,000 feet / 12 minutes = 2,000 feet per minute
Because the plane was going down, the rate of change would be negative.
The rate would be -2,000 feet per minute.
She has to put on 5 undershirt to stay 75 minutes
the answer would be 50.27m3
