Question 1180567
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?
<pre>
She leaves at 3:30 and must get to the airport at 5:30, so her time is 2 hours.

The distance = 160 km
