Acommercial jet and a private airplane flu from denver to phoenix. it takes the commercial jet 1.1 hours for the flight, and it takes the private plane 1.8 hours. the speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane

the speed of the commercial jet is 540 mph

the speed of the private airplane is 330 mph

Step-by-step explanation:

Let x represent the speed of the commercial jet and

Let y represent the speed of the private airplane.

It takes the commercial jet 1.1 hours for the flight from Denver to Phoenix.

Distance = speed × time

Therefore, distance covered by the commercial jet from Denver to Phoenix would be

1.1 × x = 1.1x

it takes the private airplane 1.8 hours to cover the same distance. The speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane. It means that

y = x - 210

Distance covered by the private airplane would be

1.8(x - 210) = 1.8x - 378

Since the distance is the same, then

1.8x - 378 = 1.1x

1.8x - 1.1x = 378

0.7x = 378

x = 378/0.7 = 540

y = x - 210 = 540 - 210

y = 330

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
