  1. Identify the total amount paid and the total hours worked.

    Sizwe is paid R450 for 3 hours.

  2. Calculate the earnings per hour by dividing the total amount by the number of hours.

    Earnings per hour=Total amount paidNumber of hours worked\text{Earnings per hour} = \frac{\text{Total amount paid}}{\text{Number of hours worked}} Earnings per hour=R4503 hours\text{Earnings per hour} = \frac{\text{R}450}{3 \text{ hours}} Earnings per hour=R150 per hour\text{Earnings per hour} = \text{R}150 \text{ per hour}

    Sizwe earns R150 per hour\boxed{\text{R}150 \text{ per hour}}.

R60 per hour\text{R}60 \text{ per hour}

  1. Identify the total amount paid and the total hours worked.

    You are paid R120 for a two-hour shift.

  2. Calculate the earnings per hour by dividing the total amount by the number of hours.

    You earn R60 per hour\boxed{\text{R}60 \text{ per hour}}.
