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.


Happy learning  (!)
