Question

Before all cars converted to unleaded gas, in a city with heavy automobile traffic, like Los Angeles, it

was estimated that about 9.0 tons of lead from automobile exhausts was deposited on or near the
freeways every day. What is this amount in kilograms per year (not a leap year)? (453.6 g = 1 pound,
1.0 ton = 2000 pounds)

Answer 1

The amount of lead deposited on or near the freeways in Los Angeles every year is approximately 8,182.4 kg.

Step-by-step explanation:

To convert tons to kilograms, we need to use the conversion factor that 1 ton is equal to 2000 pounds. Given that 453.6 g = 1 pound, we can calculate the number of kilograms.

First, let's calculate the number of pounds of lead deposited on or near the freeways every day: 9.0 tons x 2000 pounds/ton = 18,000 pounds.

Next, let's convert the pounds to kilograms: 18,000 pounds x 453.6 g/pound x 1 kg/1000 g = 8,182.4 kg.

Therefore, the amount of lead deposited on or near the freeways in Los Angeles every year is approximately 8,182.4 kg.
