Question 1021053
each car has traveled an average of 19200 kilometers.


there are 9 cars.


total kilometers is equal to 9 * 19200 = 172800 kilometers.


each car emits 150 grams of co2 emissions per kilometer.


total grams of co2 emissions is therefore 150 * 172800 = 25,920,000 grams of co2 emissions.


there are 1000 grams per kilogram.


25,920,000 grams / 1000 = 25,920 kilograms.


there are 1000 kilograms per tonne.


25,920 kilograms / 1000 = 25.920 tonnes.


round to 1 decimal place and you get 25.9 tonnes of co2 emissions.
