To find the average speed in miles per hour, you will create a rate using the number of miles to the number of hours in 45 minutes.
54 miles in 0.75 hours (45 minutes)
To make this a unit rate or miles per hour, divide the number of miles by the time.
54/0.75 = 72 mph
The train traveled an average speed of 72 mph.
Answer:
x= "a certain number of inches"
side a= x-3
side b= 2 inches
multiply:
Area= a(b)
A= (x-3)2
A= 2(x-3)
distribute:
A= 2(x-3)
A= (2*x) + (2*-3)
A= 2x-6
Area= 2(x-3)
Area= 2x-6
Step-by-step explanation:
The area of the rectangle is equal to the multiple of its two sides this is equal to two inches times an expression three less than a certain number "x". Using the distributive property, we can solve this expression further to find that the area of this rectangle is also equal to six less than doubling a certain number x.
