Question: Hilary is collecting her toenails in a jar to gross out her sister. She can fit 100 toenails in the jar, unless they are from her two big toes, which are twice as big as the rest. She has already filled it with 20 big toenails and 40 regular toenails. How many regular toenails can she fit into the remainder of the jar?
Answer with step-by-step thinking: The 20 big toenails take up as much space as 40 regular toenails because 20 x 2 = 40. She has filled up 80 toenails worth because 40 + 40 = 80. She can fit 20 regular toenails in the jar because 100 - 80 = 20.
So the answer is 20.

Question: Graeme is weighing cookies to see how many he can fit in his box. His box can only hold 40 pounds of cookies. If each cookie weighs 2 ounces, how many cookies can he fit in the box?
Answer with step-by-step thinking: First find how many cookies are in a pound. 16 ounces per pound / 2 ounces / cookie = 8 cookies per pound. The box can hold 40 pounds, so 40 pounds * 8 cookies per pound = 320 cookies.
So the answer is 320.

Question: Mr. Langsley commutes to work every day by bus. The bus picks him up at 6:00 a.m. and takes forty minutes to arrive at the first station. If Mr. Langsley arrives at work at 9:00 a.m., what's the total time taken in minutes from the first station to Mr. Langsley's workplace?
Answer with step-by-step thinking:
The total time taken for the whole journey is 9:00 - 6:00 = 3 hours. The total time taken in minutes is 3 * 60 = 180 minutes. If it takes 40 minutes to reach the first station, then the rest of the journey takes 180 - 40 = 140 minutes.
So the answer is 140.
