Question: Matt and Tom both walk up the stairs of the library. Matt goes up the stairs 20 steps per minute. Tom goes up the stairs 5 steps per minute more than Matt. If Matt has reached 220 steps above the entrance, how many steps will Tom have gone up by that time?
Answer: Matt would have walked for 220 / 20 = 11 minutes. Tom would have gone up by 11 * 5 = 55 steps more. Tom would have gone up by 220 + 55 = 275 steps. The answer is 275.
[Question]Eliza has 4 siblings. The total height of all 5 siblings combined is 330 inches. Two of her siblings are both 66 inches tall. Another sibling is 60 inches tall. If Eliza is 2 inches shorter than the last sibling, how tall is Eliza?
[Answer]The first three siblings are 66 + 66 + 60 = 192 inches tall. Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = 138 inches tall combined. If Eliza's height = h, 138 inches = h + (h + 2). (138 - 2) / 2 = 68 inches. Eliza is 68 inches tall. The answer is 68.
