Question for:

According to the California Air Resources Board, within 100 miles/kilometers, how far would you have to drive a new, light-duty passenger car in order to emit the same amount of smog-forming pollution as operating a commercial gas-powered leaf blower for one hour? (important note: round your answer to the nearest hundred - thus, there will be three correct answers in each measurement. Submit answer in the form: "xx miles" or "xx km". A number only answer WILL NOT be accepted - "miles" or "km" MUST be in your answer.)
