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



Answer:Speed can be defined as
Explanation: B because if you think about it, 50 milers per hour means they are dividing the time it takes to drive a certain distance going that speed. So id has to be answer B! your welcome. Please upvote only if its correct!
If everything else is held constant ... the substance from which
the conductor is formed, its cross-sectional area, its temperature
everywhere along its length ... then yes, its resistance will be
directly proportional to its length.
