You should look to units of measure when setting up problems. when math is done correctly, the units cancel out just as numbers and variables do.
(miles / hr) * hr = miles
Speed = (miles / hr)
So if the Train W is traveling at x miles/hr
Then Train E is traveling (x+14) miles/hr
The combined distance they two trains travel is 320 miles
2x + 2(x+14) = 320
2x + 2x + 28 = 320
4x + 28 = 320
4x = 292
x = 292/4
x = 73 miles/hr
remember we set x as the speed for Train W
so Train E is going 73 + 14 = 87 miles/hr

Answer:
quart
Step-by-step explanation:
Given:
Riley drink 4/5 quart of iced tea
And her friend drink 0 3/10 quart of iced tea
Question asked:
how much more of a quart of iced tea did Riley drink than her friend = ?
Solution:
Riley drank of iced tea = 
Her friend drank of iced tea = 
= 
We will subtract the share of her friend from Riley's share
Riley drank more than her friend =
= 
= 
Thus, Riley drank
quart more than her friend.

Determine which has a better value
First, we calculate the unit rate of both.

For the family size:


For the mega size:


<em>By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate</em>
