In Mathematics and Geometry, a proportional relationship is a type of relationship that passes through the origin (0, 0) and produces equivalent ratios as represented by the following mathematical equation:
y = kx
Where:
- y represents the y-variable or time (min).
- x represents the x-variable or distance (km).
- k is the constant of proportionality.
Next, we would determine the constant of proportionality (k) by using various data points as follows:
Constant of proportionality, k = y/x
Constant of proportionality, k = 1/2 = 2 1/2/10
Constant of proportionality, k = 1/2
Therefore, the required linear equation for y(c) is given by;
y = kx
y = 1/2(x).
When x is 5, the value of t is given by;
y = 1/2(5)
y = 5/2 or 2.5
