Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o

1 minute = 60 seconds.
1/4 of a minute = 15 seconds.
She waited 3 minutes 15 seconds for the bus.
1/2 minute = 30 seconds
She rode the bus for 7 minutes 30 seconds.
Her total time was:
8 minutes 45 seconds + 3 minutes 15 seconds + 7 minutes 30 seconds =
19 minutes and 30 seconds.
Add 19 minutes and 30 seconds to 6: 45 am,
6:45 + 19 minutes 30 seconds = 7:04:30 am
The mixed number would be larger depending on what it is...
