One horsepower is equivalent to which of the following in BTU per minute?

Explanation:
Power is how fast work is done, so we convert horsepower to a BTU-per-minute rate by using consistent energy-per-time units. One mechanical horsepower is 550 ft·lb of work each second. Convert to per minute: 550 × 60 = 33,000 ft·lb per minute. Since 1 BTU equals about 778.169 ft·lb, the BTU per minute value is 33,000 ÷ 778.169 ≈ 42.4. So one horsepower is about 42.4 BTU per minute. The other numbers don’t fit because they would require different power values that don’t match the defined conversion.
