The equation of the car rental company in the form y = kx is; y = 18.50x
The equation y = kx is such that;
- k = constant of proportionality.
In essence; to determine the constant of proportionality, k in this case;
Since the company charges, $55.50 for 3 days; we have;
By evaluation k = $55.50/3
A constant rate of change means the variation in the dependent variable as dependent on the independent variable is constant

Answer:
The correct answer is Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.
Step-by-step explanation:
Let the speed of Cruz when running is s miles per hour and speed of cruz biking is 1.6s miles per hour.
Cruz ran for 90 minutes and rode is bike for 135 minutes.
Total distance covered by Cruz is
× s + 1.6s × 
This distance is given to be 51 miles.
⇒
× s + 1.6s ×
= 51
⇒ 90s + 216s = 3060
⇒ 306s = 3060
⇒ s = 10
Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.
