An oil spill covers 4 square kilometers in 14 of an hour. At this rate, how many square kilometers will it cover in 2 hours?(1 point)
Responses
32 square kilometers
32 square kilometers
16 square kilometers
16 square kilometers
2 square kilometers
2 square kilometers
8 square kilometers
To find the answer, we can set up a proportion:
4 square kilometers / (14 of an hour) = X square kilometers / 2 hours
Cross-multiplying, we get:
4 square kilometers * 2 hours = (14 of an hour) * X square kilometers
Simplifying, we get:
8 square kilometers = (14/1) * X square kilometers
Dividing both sides by 14, we get:
8/14 = X
Simplifying, we get:
4/7 = X
Therefore, the oil spill will cover 4/7 square kilometers in 2 hours. This is approximately 0.57 square kilometers.
not in a fraction
I apologize for the confusion. We already have the proportion set up as:
4 square kilometers / (14 of an hour) = X square kilometers / 2 hours
To solve for X, we can cross-multiply:
4 square kilometers * 2 hours = (14 of an hour) * X square kilometers
Simplifying, we get:
8 square kilometers = 14X square kilometers
Dividing both sides by 14, we get:
8/14 = X
Simplifying, we get:
4/7 = X
Therefore, the oil spill will cover approximately 4/7 square kilometers in 2 hours.
what is another number for 4/7
Another number for 4/7 is approximately 0.5714.
To find out how many square kilometers the oil spill will cover in 2 hours, we can set up a proportion based on the given information.
We know that the spill covers 4 square kilometers in 1/4 (14 of an hour) of the time. Let's set up the proportion:
4 square kilometers / (1/4 hour) = x square kilometers / 2 hours
To solve for x, we can cross multiply and then divide:
4 * 2 = (1/4) * x
8 = (1/4) * x
To isolate x, we can multiply both sides of the equation by 4:
8 * 4 = x
32 = x
Therefore, the oil spill will cover 32 square kilometers in 2 hours.
To find out how many square kilometers the oil spill will cover in 2 hours, we need to use the given rate of 4 square kilometers in 1/4 of an hour.
First, let's calculate how many of these 1/4-hour periods are in 2 hours. Since there are 60 minutes in an hour, 2 hours would be equal to 2 * 60 = 120 minutes.
Since each 1/4-hour period is equal to 15 minutes (1/4 * 60 = 15 minutes), we can find out how many of these periods are in 120 minutes by dividing 120 by 15.
120 minutes / 15 minutes per 1/4-hour = 8 1/4-hour periods
Therefore, the oil spill will cover 4 square kilometers * 8 periods = 32 square kilometers in 2 hours.
So the answer is 32 square kilometers.
