The property of a(b+(-b))=(b+(-b))a is called as Commutative Property of Multiplication.
The Commutative Property in mathematics is a rule that allows interchange the order of terms or factors without any change in the end result.
In multiplication, we can interchange the factors without affecting the end result of multiplication. For example, 2 x 3 = 3 x 2 = 6
In addition, we can interchange the terms without affecting the summation result. For example, 2+3 = 3+2 = 5
But Commutative Property does not apply to subtraction or division.
For example, 2-3 != 3-2
or, 2/3 != 3/2
Hence the answer to the question is Commutative Property of Multiplication.

Answer:
- speed of the first bus: 36 2/3 miles per hour
- speed of the second bus: 73 1/3 miles per hour
Step-by-step explanation:
The second bus travels twice as fast, so will take half the time of the first bus. The second bus takes 3 hours less time, so that is half the time of the first bus.
The first bus's speed is (220 mi)/(6 h) = 36 2/3 mph.
The second bus's speed is twice that: 73 1/3 mph.
