Question

An oil spill is growing at a rate of 68.47 cm2/min, how many km2/day is this?

Answer 1

68.47 square centimeters per minute equals 9.860 × 10⁻⁶ square kilometers per day.

Step-by-step explanation:

From Physics we get that a square kilometer equals 10¹⁰ square centimeters and a day equals 1440 minutes. Then, oil spill growth rate is found by making this conversion:

`x = 68.47\,(cm^(2))/(min)* (1\,km^(2))/(10^(10)\,cm^(2)) * (1440\,min)/(1\,day)`

`x = 9.860* 10^(-6)\,(km^(2))/(day)`

68.47 square centimeters per minute equals 9.860 × 10⁻⁶ square kilometers per day.
