You're welcome.
18.75
To solve this problem, we need to find the time it takes to plant one plant. We can then multiply this time by the number of plants we want to find the total time.
First, let's calculate the time it takes to plant one plant. We know that it takes 45 minutes to plant 12 plants. Therefore, to find the time for one plant, we can divide 45 minutes by 12 plants:
Time for one plant = 45 minutes ÷ 12 plants
By dividing, we find that it takes 3.75 minutes to plant one plant.
Now that we know the time it takes to plant one plant (3.75 minutes), we can find the time it takes to plant 5 plants by multiplying the time for one plant by 5:
Time for 5 plants = Time for one plant × 5 plants
= 3.75 minutes × 5 plants
Multiplying, we find that it takes 18.75 minutes to plant 5 plants.
Therefore, it takes approximately 18.75 minutes to plant 5 plants.
