Multiply these numbers and there’s your answer
Answer:

Explanation:
From the question we are told that:
Length 
Width 
Velocity of Car A 
Velocity of Car B 
Distance traveled by car A before car B moves


Therefore total distance traveled at same time interval

Where
Total distance=Perimeter of rectangle



Therefore


Generally the equation for time taken to meet is mathematically given by

Where
Relative speed = Speed of car A +Speed of car B



Therefore the time taken to meet



by the wind and air flow in the wind
Sector-specific technological measures – vapor recovery nozzles at gasoline pumps, cleaner-burning fuels, strong vehicle inspection programs and strict emission limits for refineries, industrial emissions and combustion sources – all can help control ozone pollution and have contributed to lower emissions over the last three decades
