20,028 feet is 3.793 miles
The summit of Mt. Everest is 29,029 ft above sea level. That's 5.498 miles.
Answer:
The temperature after half an hour is 
Solution:
As per the question;
Metabolic rate of the person is 3.0105 J/h
Temperature, T = 
Mass of the water, 
Time duration, t = 0.5 h = 30 min = 180 s
Now,
Heat, 
Thus heat transfer in half an hour:
Now, the temperature of water after half an hour, T' is given by:
where
s = 4186 J
D. Binary Stars
