Q: Marcy keeps a 2-liter bottle of water by her desk. She takes a sip every five minutes, and each sip is 40 ml. How many minutes does it take her to drink the whole bottle of water?
A: First find the total number of milliliters in the bottle: 2 liters * 1000 ml / liter = 2000 ml. Then divide the total number of milliliters by the amount she drinks per sip: 2000 ml / 40 ml = 50 sips. Then multiply the number of sips by the time per sip to find the time it takes her to drink the bottle: 50 sips * 5 minutes / sip = 250 minutes. The answer is 250.

[Question]Debbie works at a post office packing boxes to mail. Each large box takes 4 feet of packing tape to seal, each medium box takes 2 feet of packing tape to seal, and each small box takes 1 foot of packing tape to seal. Each box also takes 1 foot of packing tape to stick the address label on. Debbie packed two large boxes, eight medium boxes, and five small boxes this afternoon. How much tape did she use?
[Answer]Debbie used 4 * 2 = 8 feet of tape for the large boxes. She used 2 * 8 = 16 feet of tape for the medium boxes. She used 1 * 5 = 5 feet of tape for the small boxes. There were 2 + 8 + 5 = 15 boxes in all. She used 1 * 15 = 15 feet of tape for the address labels. Thus, she used 8 + 16 + 5 + 15 = 44 feet of tape in all. The answer is 44.
Q: Brenda raises mice, and her adult mice recently had three litters of 8 each. She gave a sixth of the baby mice to her friend Robbie to keep as pets. She sold three times the number of babies she gave Robbie to a pet store. Half of the remaining mice were sold to snake owners as feeder mice. How many baby mice did Brenda have left?
A: Brenda's mice had 3 * 8 = 24 baby mice. She gave Robbie 24 / 6 = 4 mice. Thus, she sold 3 * 4 = 12 mice to the pet store. She had 24 - 12 - 4 = 8 mice remaining. She sold 8 / 2 = 4 as feeder mice. Thus, Brenda had 8 - 4 = 4 mice left. The answer is 4.
Question: The trip from Philip's house to the children's school is 2.5 miles, and the trip to the market is 2 miles. He makes the round trip to school two times (when taking the children to school and when bringing them back) every day for 4 days a week. Then he makes a round trip to the market once during weekends. What is his car's mileage for a typical week?
Answer: Making the round trip to school means driving from the house to school and then back, for a total of 2.5 + 2.5 = 5 miles. He makes this trip twice in one day for a total of 2 * 5 = 10 miles. He does this 4 times in a week for a total of 4 * 10 = 40 miles. The round trip (once a week) to the market is 2 + 2 = 4 miles. His total mileage for a typical week = 40 + 4 = 44 miles. The answer is 44.
