The direct variation that can be established using the given parameters is that, the time it takes between seeing the lightning and hearing the thunder is directly related to the speed.
However, it can also be established that the time described above is inversely proportional to the distance. This can be written as, t = k/d We substitute the given expression for each of the known terms. t is time, s, and d is distance, 3s.
s = k/3s
The k written in the equation is the constant of proportionality.
The original perimeter is 32ft. The dimensions of the new rectangle are 72 ft wide and 24 ft long. The new perimeter is 192 ft. When the dimensions are multiplied by 6, the perimeter also multiplied by 6.
