You can put this solution on YOUR website! Annie needs to catch a plane at the airport which will leave by 6:00pm. If
she leaves her house at 3:30pm and the airport is 160 km. away, at what
speed should she travel to arrive at the airport 30 minutes before the plane
takes off?
She leaves at 3:30 and must get to the airport at 5:30, so her time is 2 hours.
The distance = 160 km

It is so simple . . . that I do not understand why you are so worried.
From the text and from the context, Annie has 2 hours, from 3:30 pm to 5:30 pm, to get the airport.
She will reach the airport in 2 hours, if her rate of travel on the road/highway will be
160 kilometers divided by 2 hours = = 80 km/h. ANSWER
Solved, answered, and carefully explained.
It is one of typical and simplest Travel @ Distance problems for beginners.
Every person who drives a car and is planning his (or her) time ahead, solves such problems MENTALLY every day.
And for normal student / person / driver it takes 3 - 5 seconds to solve it mentally -
approximately the same time as to look in his or her wristwatch on his or her hand.
