Answer: The solution is 
Step-by-step explanation:
since we have given that

we need to solve it using area models:
As we know that "In fractions, division is changed into multiplication by reciprocating the next term to make it possible to solve":
So, It turns into model of area "Area of rectangle "

Now, verifying by using numerical operations only.

Hence, verified.
The answer is -5(x+6y+10)
Area: 450m×400m= 180,000m
1m = .001km
converting meters to kilometers
180,000m× .001km= 180km
The 60 represents the rate at which the train is traveling in km per hour. So, I believe the answer would be D (sorry if this is wrong, to be honest I’m just using context clues)
