Question and rationale:
The question is: 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?
Step-by-step reasoning process: 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.
