The kilopascal is a unit of measure for atmospheric pressure. suppose the atmospheric air pressure at sea level is about 101 kilopascals. for every 1000-m increase in altitude, the pressure decreases about 11.3 %. what is the approximate pressure at an altitude of 2000 m?
the pressure at an altitude of 2000 m is about kilopascals.

The pressure at an altitude of 2000 m is about 79 kilopascals.

Step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
