Answer:
This is the commutative property of multiplication.
Step-by-step explanation:
We know this because that property states that it does not matter what order the numbers are multiplied together, as long as they are all being multiplied. So even though the numbers change on both sides, it does not affect the answer.

Answer:
Linear equation of train is:
x =62.5t
Step-by-step explanation:
Given a train A.
Train A can travel 500 miles in 8 hours.
so in one hour this train a can travel 500/8 miles
i.e train A travel distance in one hour = 500/8 = 62.5 miles
That meas speed of train= 62.5 miles/hour
Since the travelling rate of train is constant.
So we can write a linear equation that represents the situation.
Let the distance covered by train in t hours be x miles.
or Distance covered by train = Speed of train * time
or x = 62.5 * t , where t is the time in hours.
or x =62.5t
