Ahot air balloon went from an elevation of 6,678 feet to an elevation of 3,438 feet in 48 minutes. what was its rate of descent?

The rate  of descent is

Step-by-step explanation:

we know that

The formula to calculate the rate or slope between two points is equal to

Let

x------> the time in minutes

y----> the elevation in feet

we have

Substitute the values

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
