Answer:

Peter will complete the job in 8 hours

Explanation:

Notice that 5 1/3 hours is 16%2F3 hours.

So, their combined rate of work is 1%2F%28%2816%2F3%29%29 = 3%2F16 of the job per hour.

Steven's rate of work is 1%2F16 of the job per hour.

Hence, Peter's rate of work is the difference 3%2F16 - 1%2F16 = 2%2F16 = 1%2F8 of the job per hour.

It implies that Peter will complete the job in 8 hours, working alone.
