Question

average number of vehicles checked in a certain time period
from pollution check centre

Answer 1

Passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

Answer 2

The average number of vehicles checked are 300 to 350.

Explanation:

• The emissions and engine capacity of vehicles are different and hence they require different times for the checking process.
• If the emissions are high, then the control over the vehicles is difficult.
• Some vehicles use less fuel and they fall under the easy check process.
• Consumption of fuel and the engine capacity determines the time taken to check pollution levels of each vehicle.
• On average, only 300 vehicles can be checked per month to reduce the workload of the safety departments.
