J=(72/60) floors upward per second
m=(48/60) floors downward per second

j=m at 20 seconds. At 20 seconds they'll both be at floor 42

Jek will go up 24 floors in 1/3minute and maitress will travel down 16 floors in 1/3minute.

### WHAT IS THE SQUARE FOOTAGE OF A 14 BY 70 MOBILE HOME.

Hi Sharee:
The square footage is 14 times 70 equals 980 square feet.
That would be the Floor Area.
Air conditioners sometimes need to know the building volume so if you have 8 ft ceilings you would multiple 980 by 8 to get 7,840 CUBIC FEET.
Air exchange is typically are rated at cubic feet per minute and required as "specified Air Changes per Hour.
An example for your trailer would be 1/2 air change per hour required per building code. 7,840 times 1/2 equals 3920 cubic feet per hour. Divide that by 60 to get 65 cubic feet per minute.
That would be the minimum air change capacity for your air conditioner if it was also providing required ventilation.
