Verona owns a landscaping company, and she is mulching all of the flowerbeds at the houses in a planned retirement community. The figure shows the layout of the neighborhood and the times that Verona started mulching the flowerbeds at two of the houses. According to the architect’s plans for the community, the flowerbed for each house is approximately 0.006 acres in size.
NOTE: The image shows 34 houses and the timings are 8am to 9:20 am (takes 5 hours for that much time).
How many minutes will it take Verona to mulch all of the flowerbeds in the community? Please provide me with an explanation because the answer key says the answer is 680 but I got 544 mins.
