Answer 1

The distance between Atlanta, GA and Albuquerque, NM, is about 1270 miles. The groundspeed for jet traffic from Albuquerque to Atlanta can be about 18% faster than the groundspeed from Atlanta to Albuquerque. Let r be the speed from Atlanta to Albuquerque in miles per hour. What is the simplified expression for the round-trip flying time?

Answer 2

@radar come help please!

Answer 3

The problem is saying for this two way trip the ground speed for the jet plane is 18% faster when traveling to Atlanta from Albuquerque. It then it instructs you to label the speed from Atlanta to Albuquerque as "r" in mph. Now the distance between these two cities is given as 1,270 miles and is the same for each leg of the trip.

Use the formula d=rt where distance is d, speed is r and time is t. now solve for t.
t = d/r. We want the total roundtrip travel time, so we must use the appropriate speed
the two speeds will be r (going to Albuquerque and 1.18r (18% faster r). Our complete equation will now look like this: t(total)= 1270/r + 1270/1.18r

Did you follow that.

Answer 4

yeah. Thank you @radar

Answer 5

There is the expression, there is no value as no speed value was given.
