You enter a relay race. to start, you must run 20 yards to checkpoint a. you then must turn and run 12 yards to checkpoint b. last, you must turn and run back to the starting line. what is the distance from checkpoint b to the starting line? : )

Distance to checkpoint A from starting line = 20 yards.

Then from A to B distance = 12 yards.

Let us take starting point C.

So, it would make a right triangle.

We have AB = 12, AC = 20, we need to find BC, that is Hypotenuse of the right triangle.

According to Pythagoras theorem:

BC = 23.32.
