an oil spill covers 4 square kilometers in 1/4 of an hour. At this rate, how many square kilometers will cover in 2 hours? Show your work
A. 2
B. 32
C. 8
D.16
To find the number of square kilometers that will be covered in 2 hours, we need to find the rate at which the oil spill spreads in 1 hour and then multiply that by 2.
Since the oil spill covers 4 square kilometers in 1/4 of an hour, we can find the rate in 1 hour by multiplying both sides of this equation by 4:
4 square kilometers / (1/4 hour) = 4 * 4 = 16 square kilometers/hour
To find the amount of square kilometers that will be covered in 2 hours, we multiply the rate by the number of hours:
16 square kilometers/hour * 2 hours = 32 square kilometers
Therefore, the oil spill will cover 32 square kilometers in 2 hours.
The answer is B. 32
