Question

PLEASE HELP!!

What is the time to go round trip in an airplane flight?
Describe the real world situation. Write the addition or subtraction rational expression to represent your situation. Simplify the expression, showing your work or explaining the steps using complete sentences.

Answer 1

flight from where to where?

Answer 2

it doesnt matter, you can make it up

Answer 3

takes about 5 hours to fly across the country
look up any flight and see how long it takes

Answer 4

virginia to california takes 4 hours

Answer 5

ok then the round trip would take about 8
i am thinking there is more to this question, because that seems painfully easy

Answer 6

well we have to write a rational expression

Answer 7

then simplify showing the steps

Answer 8

then i am confused, because it seems like all you would have to do it double the one way time to get the round trip time
sorry i cannot be more help
do you have some worked out example?

Answer 9

that part is right, but i have to right a rational expression to represent the situation

Answer 10

yeah i don't get how to do that
rational expressions look like
\[\frac{x-1}{x+2}\] and i cannot imagine how you would use that in this case

Answer 11

well this is the full question:
Think about a kayaking race, a round trip airplane flight, a shopper on an escalator, or a swimming competition.

Choose an activity where a rational expression can represent the total or difference of time. For example, what is the time to go round trip on a hot air balloon ride?
