A Lawyer can solve 32 math riddles per hour, and his friend Sam takes three hours to solve the same number.
If they both work on them, how long will it take for them to solve 32 math riddles?
Answer: If a lawyer solves them three times as fast, he would be solving 24 of the 32 riddles, while Sam did 8 of them.
Since 24 is 3/4 of 32, it would take 3/4 of an hour, or 45 minutes for the two of them to solve the 32 math riddles.
