During the first 50 minutes of flight, the Concorde climbs from ground level to an altitude of about 52,000 ft. What is the conc

horsena [70]

Let

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

y-------> an altitude in feet

we know that

For x=0 min y=0 ft

For x=50 min y=52,000 ft

the rate of change is equal to calculate the slope of the linear equation

$\frac{52,000-0}{50-0}=\frac{52,000}{50}=1,040\frac{ft}{min}$

Round to the nearest hundred--------> $1,000\frac{ft}{min}$

therefore

the answer is

$1,000\frac{ft}{min}$
