The white rabbit can hop 15 meters in one minute. The brown rabbit hops 12 meters per minute. What is the total distance the two rabbits will hop in 5 minutes? Give the rationale and then the answer.
Let's think step by step. White rabbit + brown rabbit = 15 + 12 = 27. 5 minutes * 27 = 135 meters. The two rabbits will hop 135 meters in 5 minutes.. The answer is: 135.

Hannah's AdBlock blocks all but 20% of ads, and 20% of the ads it doesn't block are actually interesting. What percentage of ads aren't interested and don't get blocked? Give the rationale and then the answer.
Let's think step by step. First find the percentage of ads that aren't interesting: 100% - 20% = 80%. Then multiply that percentage by the percentage of ads that don't get blocked to find the percentage of ads that meet both criteria: 80% * 20% = 16%.. The answer is: 16.
