The small plane has the following parameters
Distance = 1200 miles
Speed = 300miles/hour
time = ?

If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours
Considering the distance of the small plane after 6 hours, we have

So the total distance = 1800 miles
Hence the speed of the Boeing 747 will be


The average speed of the Boeing 747 is 900 miles/ hour
Answer:
−16(2−−5)
Step-by-step explanation:
hay un factor común entre estos números, por lo que simplemente −16t2+16t+80 divida y reutilice y luego reciba−162+16+80 llegar
−16(2−−5)
700-175=525
525:35=15

Answer:
Step-by-step explanation:
A hole is an input value that makes both numerator and denominator equal to zero.
In other words, same factor in both numerator and denominator.
<u>Let's factorize the denominator:</u>
- x² - 7x + 10 = x² - 5x - 2x + 10 = x(x - 5) - 2(x - 5) = (x - 2)(x - 5)
<u>We have same factor of x - 5:</u>
