The concentration of the car exhaust fume nitrous oxide, NO2, in the air near a busy road is a function of distance from the road. The concentration decays exponentially at a continuous rate of 2.54% per meter.¹ At what distance from the road is the concentration of NO₂ half what it is on the road? Round your answer to the nearest integer. At i meters from the road the concentration of NO₂ in the air is half the concentration on the road. At what distance from the road is the concentration of NO₂ 10% of what it is on the road? At i meters from the road the concentration of NO2 in the air is 10% of the concentration on the road.
