1. How much water must be evaporated from 17 qt of a 65% antifreeze solution to produce an 85% solution?  2. Two planes are 495 mi apart and are traveling toward each other. One plane is traveling 150 mph faster than the other plane. The planes pass each other in 0.5 h. Find the speed of each plane.  3.  A commuter plane provides transportation from an international airport to the surrounding cities. One commuter plane averaged 200 mph flying to a city and 120 mph returning to the international airport. The total flying time was 4 h. Find the distance between the two airports.

Expert Answer

Step 1

If mentioned: Since you have submitted three questions, we'll answer the first question. For the other two questions please submit the questions again and specify it.

Let x qt must be evaporated .

Step 2

So new amount of the solution is = (17-x).

It is 85% solut...
