An oil spill covers 4 square kilometers in & of an hour. At this rate, how many square
kilometers will it cover in 2 hours?
If an oil spill covers 4 square kilometers in 1 hour, then the rate of coverage is 4 square kilometers per hour.
To find out how many square kilometers the spill will cover in 2 hours, we multiply the rate of coverage by the number of hours: 4 square kilometers/hour * 2 hours = <<4*2=8>>8 square kilometers. Answer: \boxed{8}.
