Answer:
3.5 hours*3.25 mph=11.375 miles
11.375 miles/3.45 mi/hr=3.297 hours or 3.30 hours, about 12 minutes faster.
Step-by-step explanation:
For this case we have that the complete question is:
There were 20 drinks in a cooler. Joey drank 15% of the drinks. Sandra drank 1/5 of the drinks. Hannah drank 1/4 of the drinks. Tammy drank 30% of the drinks. How many drinks are left in the cooler? a 0 b 2 c 5 d 9
We propose a rule of three:
20 ---------> 100%
x ------------> 15%
Where the variable "x" represents the amount of drinks equivalent to 15%.

So, Joey drank 3 drinks.
On the other hand, we have that Sandra drank
of the drinks:

Thus, Sandra drank 4 drinks.
In addition, Hannah drank
of the drinks:

So Hannah drank 5 drinks.
Finally, Tammy drank 30% of the drinks:
20 ---------> 100%
y ------------> 30%
Where the variable "y" represents the amount of drinks equivalent to 30%.

So Tammy drank 6 drinks.
Adding up we have:

So: 
Thus, 2 drinks remain in the refrigerator.
