Question: Janet starts driving across a lake in a speedboat going 30 miles per hour. Her sister follows in a sailboat that has a speed of 12 miles per hour. If the lake is 60 miles wide, how long does Janet have to wait on the other side for her sister to catch up?
Answer: First find how long it takes Janet to cross the lake: 60 miles / 30 miles / hour = 2 hours. Then find how long it takes her sister to cross the lake: 60 miles / 12 miles / hour = 5 hours. Then subtract Janet's travel time from her sister's travel time to find the difference: 5 hours - 2 hours = 3 hours. The answer is 3.

[Answer]If 15% is known to be $42, then 5% can be found by dividing $42 ÷ 3 = $14. So 20% is $14 + $42 = $56. The answer is 56.
[Question]Three years ago, Rosie purchased an art piece for $4000. The same art piece will be three times as much in another three years. How much money will the art piece have increased by?
[Answer]
