How many cars have passed when a dog barks 34 times If 20 cars pass how many times will the dog bark?

If the dog barks 34 times when 20 cars pass, we can set up a ratio to find out how many times the dog would bark for a different number of cars. Assuming the relationship is linear, if 20 cars result in 34 barks, then for 1 car, the dog barks 1.7 times. Therefore, if 20 cars pass, the dog will bark 34 times.
