Carol makes birthday cards - OCR - GCSE Maths - Question 1 - 2019 - Paper 4

Now, we calculate the total time needed for 80 cards:

$\text{Total time for 80 cards} = 80 \text{ cards} \times 16 \text{ minutes per card} = 1280 \text{ minutes}$

Next, we convert minutes into hours since the working timeframe is in hours:

$\text{Total hours} = \frac{1280 \text{ minutes}}{60 \text{ minutes per hour}} \approx 21.33 \text{ hours}$

Carol works 8 hours each day for 3 days:

$\text{Total available time} = 3 \text{ days} \times 8 \text{ hours per day} = 24 \text{ hours}$

Since 21.33 hours is less than 24 hours, yes, Carol can complete the order in the given time.
