Problem #3
Science and medicine. Adriana took 2 h longer to drive 360 mi on the first day of a trip than she took to drive 270 mi on the second day. If her speed was the same on both days, what was the driving time each day?

my answer: Her driving time was 8h for her first day and 6 hours the second day.

Problem#4
Science and medicine. A plane flies 720 mi against a steady 30-mi/h headwind and then returns to the same point with the wind. If the entire trip takes 10 h, what is the plane’s speed in still air?

My answer: The speed of the plane in still air is 150mi/h




both correct.
