15 minutes is 15 / 60 = 0.25 hours. Traveling 15 minutes at 16 miles per hour, Stephen travels 16 * 0.25 = 4 miles. Traveling 15 minutes at 12 miles per hour, Stephen travels 12 * 0.25 = 3 miles. Traveling 15 minutes at 20 miles per hour, Stephen travels 20 * 0.25 = 5 miles. All together, Stephen travels 4 + 3 + 5 = 12 miles.
The answer: 12
Reverse engineering the question: Stephen rides his bicycle to church. During the first third of his trip, he travels at a speed of 16 miles per hour. During the second third of his trip, riding uphill, he travels a speed of 12 miles per hour. During the last third of his trip, he rides downhill at a speed of 20 miles per hour. If each third of his trip takes 15 minutes, what is the distance Stephen rides his bicycle to church, in miles?


Reasoning and answer: Jose can earn $3 x 8 = $24 per day for kids. He charges $3 x 2 = $6 per adult. So, he can earn $6 x 10 = $60 per day for adults. Jose earns $60 + $24 = $84 per day for kids and adults. Therefore, he can earn $84 x 7 = $588 per week.
The answer: 588
