Please help me.
One of the dangers of coal mining is the methane gas that can leak out of seams in the rock. Methane forms an explosive mixture with air at a concentration of 5% or greater, A steady leak of methane begins in a coal mine such that the concentration of methane gas vaires directly as time. Twelve minutes after the leak begins, the concentration of methane in the air is 2%. If the leak continues at the same rate, when could an explosion occur?
