To find out how many posts are along the road, you can follow these steps:
-
Convert the distance into meters: Three quarters of a kilometer is \( 0.75 \times 1000 = 750 \) meters.
-
Determine the spacing between the posts: Posts are 3.75 meters apart.
-
Calculate the number of gaps between the posts: To find the number of gaps between the posts along 750 meters, divide the total distance by the distance between the posts: \[ \text{Number of gaps} = \frac{750 \text{ meters}}{3.75 \text{ meters}} = 200 \]
-
Calculate the number of posts: The number of posts is one more than the number of gaps (because the first post starts at the beginning of the first gap): \[ \text{Number of posts} = \text{Number of gaps} + 1 = 200 + 1 = 201 \]
Therefore, there are 201 posts along the road.
