Final answer:

The power of a machine that transfers 15,000J of energy in 1 minute is calculated by dividing the energy by the time in seconds, resulting in 250 watts (250W).

Therefore the answer is option A 250 W

Step-by-step explanation:

To calculate the power of a machine that transfers 15,000 J of energy in 1 minute, we can use the formula for power, which is P = E/t, where P is power in watts, E is energy in joules, and t is time in seconds. To find the power in watts (W), we must first convert minutes into seconds. There are 60 seconds in a minute, so 1 minute is equal to 60 seconds.

Using the formula:

P = E/t
P = 15,000 J / 60 s
P = 250 W

Therefore, the power of the machine is 250 W.
