[Question]Moses and Tiffany want to see who is faster. But instead of a race, they just start running down the block. Tiffany runs 6 blocks in 3 minutes. Moses runs 12 blocks in 8 minutes. What is the speed (defined as blocks per minute) of the runner with the higher average speed?
[Answer]Tiffany runs 2 blocks per minute because 6 / 3 = 2. Moses runs 1.5 blocks per minute because 12 / 8 = 1.5. The runner with the highest average speed is Tiffany because 2 > 1.5. The answer is 2.
Q: Sarah starts saving $5.00 a week for 4 weeks. Then she saves $10.00 a week for the next 4 weeks. Then she saves $20.00 a week for the next 4 weeks. How much money has she saved over 12 weeks?
A: She starts with $5.00 a week for 4 weeks so that's 5 * 4 = $20.00. Then she bumps it up to $10.00 a week for 4 weeks so that's 10 * 4 = $40.00. After that, she saves $20.00 a week for 4 weeks so that's 20 * 4 = $80.00. Over 12 weeks she has saved 20 + 40 + 80 = $140.00. The answer is 140.
Question: It starts raining at 7:00 and pours heavily until its stops at 17:00 on a particular day. On the second day, the rain takes 2 more hours than it took on the first day to stop. On the third day, the rain pours for twice the amount of time it took on the second day. Calculate the total time it was raining in the three days.
Answer: On the first day, it rained for 17:00 - 7:00 = 10 hours. On the second day, it 10 hours + 2 hours = 12 hours for the rain to stop. It rained for 2 * 12 hours = 24 hours on the third day. In the three days, it was raining for 24 hours + 12 hours + 10 hours = 46 hours. The answer is 46.
