A train has an average speed of 18 miles per hour. How long will it take to travel 270 miles?
Answers
Step-by-step explanation:
1.) First, you need to find how many miles per hour (18), and how many miles (270)
2.) Next, you will need to divide 270 by 18, or 270/18.
3.) This will show you how many 18's you can get out of 270, or how many hours it will take to go 270 miles.
4.) After dividing, you will get 15.
Therefore, it will take you 15 hours to get from point A to point B.

What is Unit of Measurement?
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
We need to find among the given options which are greater than 2 gallons
We know that 1 gallon = 4 quarts, 1 gallon = 8 pints and 1 gallon = 16 cups
A. 5 quarts 2 pints
5/4 gallons + 5/8 gallons
= 1.875 gal
1.875<2
B. 1 gallon 3 quarts
= 1 gallon + 3/4 gallon
= 1.75 gallon
1.75<2
C. 9 quarts
= 9/4 gallons
= 2.25 gal
2.25>2
D. 40 cups
= 40/16 gallon
= 2.5 gallon
2.5>2
E. 1 gallon 9 pints
= 1 gallon + 9/8 gallon
= 2.125 gallon
2.125>2
Hence, 9 quarts, 40 cups and 1 gallon , 9 pints are greater than 2 gallons

Answer: 120 lb of potatoes.
Step-by-step explanation:
Let the pounds of potatoes sold by farmer Bill = X lb
Fractional part sold to the first person = 1/4
Therefore 1/4 of X = 1/4 x X
= X/4 lb of potatoes.
No of potatoes left for sale = X - X/4
= ( 4x - x )/4
= 3x/4 lb.
Fractional part sold to the second person out of the reminder = 4/9
Therefore 4/9 of 3x/4 = 4/9 x 3x/4
= x/3 lb of potatoes.
Amount of potatoes left for sale = 3x/4 - x/3
Resolve into fraction , we have = (9x - 4x)/12, because 12 is the LCM.
= 5x/12
Third buyer bought 4/5 of the left over = 4/5 of 5x/12
= x/3 lb of potatoes.
Amount of potatoes left = 5x/12 - x/3
Resolve in to fraction again taking 12 as the LCM = ( 5x - 4x )/12
= x/12 lb of potatoes .
Therefore, the left over was 10 lb .
To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to x/12 = 10
we now cross multiply to get the value of x x = 120 lb.
therefore the pound of potatoes sold by farmer Bill = 120 lb.

120 potatoes
