Knowing that an hour has 60 minutes, add 25 minutes to 9:55 to get 10:20. Another way to think of this is by adding 25 to 55 to the base of 60. Assuming that he only had to mow the front and back yard, add 45 minutes to 10:20 to get your final answer.
The final answer should be: 11:05 am.
If there are 3 liters of 50% acid solution, there must be 1.5 liters of pure acid and 1.5 liters of another liquid.
As it is, 1.5/x = 1/2, where x = total liters of both liquids (here, 3). We use 1.5 because that's how much we have of the other liquid.
If we set 1.5/x = 1/4, x = 6. This is 3 liters more than our original solution, and we only added pure acid.
Our answer is 3 liters of pure acid.
