Answer the following question.
Ken likes to bike when it's raining and can cycle 30 miles in 20 minutes during this time. However, when it's snowing Ken can't stand the cold and can only cycle 10 miles in 20 minutes. If it rains 3 times and snows 4 times in one week, how many miles did Ken reach if he cycles 1 hour a day?
Step-by-step reasoning process: For 1 hour on a rainy day, Ken can cycle 3 * 30 = 90 miles. For 1 hour on a snowy day, Ken can cycle 3 * 10 = 30 miles. On the rainy days this week, Ken cycled 90 * 3 = 270 miles. On the snow days of the week, Ken cycled 30 * 4 = 120 miles. In total, Ken cycled 120 + 270 = 390 miles this week.
The answer is 390.

Answer the following question.
Julia's internet speed is 20 MBps (megabytes per second). How many songs she can download in half an hour if the size per song is 5MB?
Step-by-step reasoning process: 1 hour has 60 minutes, therefore 1 / 2 hour has 1 / 2 * 60 = 30 minutes. 1 minute has 60 seconds, therefore 30 minutes has 30 * 60 = 1800 seconds. If Julia's internet speed is 20MBps and each song has a size of 5MB, then it would take 5 / 20 = 1 / 4 seconds to download one song. If it takes 1 / 4 seconds to download 1 song, then in 1800 seconds, Julia could download 1800 / (1 / 4) = 1800 * 4 = 7200 songs.
The answer is 7200.

Answer the following question.
A parking area near Peter's house is 4 stories tall. There are 4 open parking spots on the first level. There are 7 more open parking spots on the second level than on the first level, and there are 6 more open parking spots on the third level than on the second level. There are 14 open parking spots on the fourth level. How many open parking spots are there in all?
Step-by-step reasoning process: The number of open parking spots on the second level is 4 spots + 7 spots = 11 spots. The number of open parking spots on the third level is 11 spots + 6 spots = 17 spots. There are 4 spots + 11 spots + 17 spots + 14 spots = 46 open parking spots in all.
The answer is 46.
