[Question]Greg drives 30 miles from his workplace to the farmer's market. After buying his groceries at the farmers market, he drives home. To get home, he travels for 30 minutes at 20 miles per hour. How many miles in total does Greg travel?
[Answer]We must first convert minutes to hours, so 30 minutes * (1 hour / 60 minutes) = 0.5 hours. The number of miles Greg travels on his trip home is 0.5 hours * 20 mph = 10 miles. The total miles Greg travels is 10 + 30 = 40 miles. The answer is 40.

[Question]Zain has 10 more of each coin than Emerie. If Emerie has six quarters, seven dimes, and five nickels, how many coins does Zain have?
[Answer]If Emerie has six quarters, Zain has 6 + 10 = 16 quarters. At the same time, Zain has 7 + 10 = 17 dimes, ten more than Emerie. The total number of quarters and dimes Zain has is 17 + 16 = 33 coins. Zain also has 10 more nickels than Emerie, a total of 10 + 5 = 15 nickels. In total, Zain has 33 + 15 = 48 coins. The answer is 48.

[Question]Two trains left the station at the same time, but took different tracks to their destination. One took a track that was 200 miles long and it went 50 MPH. The other took the other track that was 240 miles long and it went 80 MPH. How much time did it take them on average? (Round to the nearest integer.)
[Answer]The first train took 5 hours because 200 / 40 = 5. The second train took 3 hours because because 240 / 80 = 3. The total time was 8 hours because 5 + 3 = 8. The average time was 4 hours because 8 / 2 = 4. The answer is 4.

[Question]The Diving Club offers 2 beginning diving classes on weekdays and 4 beginning classes on each day of the weekend. Each class has room for 5 people. How many people can take classes in 3 weeks?
[Answer]
There are 2 classes x 5 days = 10 classes on weekdays. There are 4 classes x 2 days = 8 classes on weekends. There are a total of 10 + 8 = 18 classes per week. So each week, 18 x 5 = 90 people can take classes. Thus, 90 x 3 = 270 people can take classes in 3 weeks. The answer is 270.
