2 and a half hours estimate

Answer:

7:20 PM.

Step-by-step explanation:

7mph+8mph=15mph

It at least has to be 1 hour(since 15 is one hour and we need 20)

double 15 and we get 30.

if you count by fives starting from 15 to 30, you should get 3.

Now, divide 60 to 3 and you get 20 min.

So, 1 hour plus 20 min is 7:20

Sue drank 2/5 of her water bottle and sally drank 4/10 of her water bottle how much water did both girls drank?
stealth61 [152]

well, clearly the LCD from the denominators of 5 and 10 is just 10, thus

\bf \stackrel{\textit{Sue}}{\cfrac{2}{5}}+\stackrel{\textit{Sally}}{\cfrac{4}{10}}\implies \stackrel{\textit{LCD of 10}}{\cfrac{(2)2~~+~~(1)4}{10}}\implies \cfrac{2+4}{10}\implies \cfrac{6}{10}\implies \stackrel{\textit{simplified}}{\cfrac{3}{5}}
