[Question]Jessica's family is 300 km away from New York. If they are traveling at the rate of 50 km/h and stop to rest for 30 minutes every 2 hours, how long will it take them to reach New York?
[Answer]Without stopping to rest they will arrive in 300 / 50 = 6 hours. They need to stop to rest after every 2 hours except for the last 2 hour stretch of time, which is when they reach New York, so they rest (6 / 2) - 1 = 3 - 1 = 2 times. The time they spend resting is 2 * 30 = 60 minutes or 1 hour. So they will arrive in 6 + 1 = 7 hours. The answer is 7.

[Question]Katy makes some brownies to eat throughout the week. She eats 5 on Monday and twice as many on Tuesday. After she has eaten the brownies on Tuesday, all of the brownies she made are gone. How many brownies did Katy make?
[Answer]On Tuesday, Katy ate 5 brownies * 2 = 10 brownies. As she has eaten all of the brownies she made, she must have made 5 Monday brownies + 10 Tuesday brownies = 15 brownies. The answer is 15.
Q: Latia wants to buy a Samsung TV worth $1700. She works for a delivery service company for a month earning $10 per hour for a 30-hour workweek. How many more hours does she have to work to buy the TV?
A: In a week, Latia earns 30 * 10 = $300. In a month, she earns 300 * 4 = $1200. If the TV was worth $1700, the total amount she has to work for to buy the TV is 1700 - 1200 = $500. Since she earns $10 per hour, she'll have to work for $500 / $10 = 50 more hours to buy the TV. The answer is 50.
Question: James takes up dancing for fitness. He loses twice as many calories per hour as he did when he was walking. He dances twice a day for .5 hours each time and he does this 4 times a week. He burned 300 calories an hour walking. How many calories does he lose a week from dancing?
Answer:
He burns 2 * 300 = 600 calories an hour. He dances for .5 * 2 = 1 hour per day. So he burns 600 * 1 = 600 calories per day. So he burns 600 * 4 = 2400 calories per week. The answer is 2400.
