Complete Question

A NASA spacecraft measures the rate R of at which atmospheric pressure on Mars decreases with altitude. The result at a certain altitude is: Convert R to

The value  is      

Explanation:

From the question we are told that

   The altitude is  

Generally  

So  

Also  

   1 km  =  1000 m

So  

=>  

Now  PA  is Pascal which is mathematically represented as

So

Looking the unit we are arrive at we see that it contains  J  which is mathematically represented as

So  

=>  

=>  

Generally  

=>      

=>  

So

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
