<span>Let t = time for the 2nd
car to catch the 1st one</span>
<span>From the problem we know car 1 is 5o
km ahead of 2nd</span>
70t=50t+50
70t-50t=50
20t=50
T = 50/20 = 2.5
They will be together after 2.5 hours, 2 hours and
30 minutes
Answers:
First bottle's unit cost = 27 cents per oz
Second bottle's unit cost = 27 cents per oz
Both have the same unit cost.
----------------------------------------
Work Shown:
unit cost = price/(number of ounces)
1st bottle unit cost = (1.35)/(5) = 0.27 dollars per oz = 27 cents per oz
2nd bottle unit cost = (2.16)/(8) = 0.27 dollars per oz = 27 cents per oz
Both lead to the same unit cost. Therefore, you can pick either option and it doesn't matter.
Answer:
