Steve plants ten trees every three minutes. If he continues planting at the same rate, how long will it take him to plant 2500 trees? Express your answer as a decimal in terms of hours.
ten trees in three minutes, is the same as
twenty threes in six minutes, is the same as
200 trees in 60 min or one hour.
time=2500/rate=2500/(200/hr)= 12.5 hrs
Well, this question is easy. I myself am a PhD in the University of Winnipeg. I am on this site answering questions for people. So here it is:
The answer is 12.5.
Well, if Steve plants ten trees every three minutes, we can calculate how many trees he plants per minute. So, he plants \(\frac{10}{3}\) trees per minute.
Now, to find out how long it will take him to plant 2500 trees, we can divide the total number of trees by the number of trees he plants per minute:
\(\frac{2500}{\frac{10}{3}} = 750\) minutes.
But we need our answer in terms of hours, not minutes. So, let's convert 750 minutes to hours by dividing it by 60:
\(\frac{750}{60} = 12.5\) hours.
Therefore, it will take Steve approximately 12.5 hours to plant 2500 trees.
To find out how long it will take Steve to plant 2500 trees, we can set up a proportion based on the rate at which he plants trees.
In 3 minutes, Steve plants 10 trees.
So, in 1 minute, Steve plants 10/3 trees (since 10 trees / 3 minutes = 10/3 trees/minute).
Let's now find out how many minutes it will take to plant 2500 trees. We can set up the following proportion:
(10/3) trees/minute = 2500 trees/x minutes
To solve for x, we cross-multiply and divide:
(10/3) * x = 2500
10x = 7500
x = 7500/10
x = 750
Now we know it will take Steve 750 minutes to plant 2500 trees.
To express the answer in terms of hours, we can divide 750 minutes by 60 (since there are 60 minutes in an hour):
750 minutes / 60 minutes/hour = 12.5 hours
Therefore, it will take Steve 12.5 hours to plant 2500 trees.
