If a machine is doing 500 J of work with 75 watts of power, how long did it take to complete its task? (Round your answer to the nearest 10th (0.1))

8.9

To determine the time it took for the machine to complete its task, we can use the formula:

Work (W) = Power (P) x Time (t)

Given that the machine did 500 J of work and had a power output of 75 watts, we can rearrange the formula to solve for time:

t = W / P

Plugging in the values:

t = 500 J / 75 W

Now, we can calculate the time:

t = 6.67 seconds

Rounding to the nearest tenth, the machine took approximately 6.7 seconds to complete its task.
