To find the answer, we need to determine the rate at which the oil spill covers the area. The oil spill covers 4 square kilometers in 1/4 of an hour, so to find the rate at which it covers the area in one hour, we multiply 4 by 4, which equals 16 square kilometers.
Therefore, the oil spill will cover 16 square kilometers in 1 hour.
To find how many square kilometers it will cover in 2 hours, we multiply the rate of 16 square kilometers/hour by 2, which equals 32 square kilometers.
So, the correct answer is 32 square kilometers.
To calculate how many square kilometers the oil spill will cover in 2 hours, we need to find the rate at which it covers the area.
Given that the oil spill covers 4 square kilometers in 14 of an hour, we can find the rate by dividing the area covered by the time taken:
Rate = Area / Time
Rate = 4 square kilometers / (1/14) hour
To find the rate per hour, we can multiply the rate by 60 (since there are 60 minutes in an hour):
Rate per hour = (4 square kilometers / (1/14) hour) * 60
Simplifying this equation, we have:
Rate per hour = 4 * (14/1) * 60
Rate per hour = 4 * 14 * 60
Rate per hour = 3360 square kilometers per hour
Now, we can calculate the area covered in 2 hours:
Area covered in 2 hours = Rate per hour * Time
Area covered in 2 hours = 3360 square kilometers per hour * 2 hours
Area covered in 2 hours = 6720 square kilometers
Therefore, the oil spill will cover 6720 square kilometers in 2 hours.
To solve this problem, we can calculate the oil spill's rate of coverage per hour and then use that information to find out how much it would cover in 2 hours.
First, we need to find the oil spill's rate of coverage per hour. We are given that it covers 4 square kilometers in 14 of an hour. To find the coverage per hour, we can use a proportion.
Let's set up the proportion:
(4 square kilometers) / (14 of an hour) = X square kilometers / 1 hour
Now, we can cross multiply and solve for X:
(4 square kilometers) * (1 hour) = (14 of an hour) * X square kilometers
4 = 14X
Divide both sides by 14:
4 / 14 = X
X ≈ 0.2857
So, the oil spill covers approximately 0.2857 square kilometers per hour.
Now, we can find how much it would cover in 2 hours. We multiply the rate per hour by the number of hours:
0.2857 square kilometers/hour * 2 hours = 0.5714 square kilometers
Therefore, at this rate, the oil spill would cover approximately 0.5714 square kilometers in 2 hours.
