Question

Rosa has a lot of cones! She put down one cone outside of her house. She then walked three thousand inches and put down another cone. She kept doing this. By the time she put down her last cone, she had walked thirty thousand inches. How many cones did she put down?

A. 110 cones
B. 120 cones
C. 130 cones
D. 140 cones

Answer 1

Rosa placed a total of 31 cones, one at the starting point and one for every 3,000 inches walked, resulting in 10 additional cones for the 30,000 inches traveled, which is not listed in the provided options.

Step-by-step explanation:

Rosa laid down a total of 31 cones. She placed the first cone at the starting point, which doesn't count as having walked any distance yet. For every 3,000 inches, she placed another cone. To calculate the number of cones, we divide the total distance walked by the distance between cones. So, 30,000 inches divided by 3,000 inches gives us 10 cones, but we must add the first cone that she placed at the start resulting in a total of 11 cones. Therefore, none of the options (A-D) listed in the question are correct.
