To find out how many square kilometers the oil spill will cover in 2 hours, we can first determine its rate of coverage per hour.
Since the spill covers 4 square kilometers in 1/4 of an hour, we can multiply that rate by 4 to find the coverage per hour.
4 square kilometers/ (1/4) hour = 16 square kilometers per hour
Therefore, in 2 hours, the oil spill will cover:
16 square kilometers per hour * 2 hours = 32 square kilometers.
So the correct option is 32 square kilometers.
To find out how many square kilometers the oil spill will cover in 2 hours, we need to calculate the rate at which it is spreading.
Given that the oil spill covers 4 square kilometers in 14 of an hour, we can find the rate of coverage by calculating:
Rate = Area/Time
Rate = 4 square kilometers / (14 of an hour)
To calculate the rate per hour, convert 14 of an hour to an hour:
1 hour = 60 minutes
14 of an hour = (14/60) * 1 hour = 0.2333 hours
Rate = 4 square kilometers / 0.2333 hours
Now, we can calculate the rate of coverage per hour:
Rate = 17.14 square kilometers/hour (approximately)
Finally, we can calculate how many square kilometers the oil spill will cover in 2 hours:
Coverage = Rate * Time
Coverage = 17.14 square kilometers/hour * 2 hours
Coverage = 34.28 square kilometers (approximately)
Therefore, the oil spill will cover approximately 34.28 square kilometers in 2 hours.
To find out how many square kilometers the oil spill will cover in 2 hours, we need to first determine the rate at which it is spreading.
Given that the oil spill covers 4 square kilometers in 14 of an hour, we can calculate the rate as follows:
Rate = Area / Time
Rate = 4 square kilometers / 14 hour
Simplifying this, we find that the rate of spread is:
Rate = 2/7 square kilometers per hour
Now, to determine how many square kilometers the oil spill will cover in 2 hours, we can multiply the rate by the time:
Area = Rate * Time
Area = (2/7 square kilometers per hour) * 2 hours
Calculating this, we find:
Area = 4/7 square kilometers
Therefore, the oil spill will cover approximately 4/7 square kilometers in 2 hours.
