First thing: Stop typing your posts in ALL CAPS. It is the electronic equivalent of shouting and is therefore both annoying and unacceptably rude behavior.
Use distance equals rate times time or
Rearrange it so that time is expressed in terms of distance and rate, thus:
So, the time required for the car to travel 50 miles is:
where is the speed of the car.

Now you can write a statement for the time it takes the plane to travel 180 miles:
But the problem says that these two times are equal, so:
