Question

If your car is traveling at a constant rate of speed the distance is proportional to the time if a car travels 165 miles in 2.5 hours write a linear equation in two variables that represents the number of miles y the car can travel in X hours

Answer 1

y = 66x

Explanation:

A proportional relationship is described by the linear equation ...

y = kx

where k is the "constant of proportionality."

The value of k can be found from the given values of y (miles) and x (hours).

k = y/x . . . . . divide both sides of the proportional relation by x

k = (165 miles)/(2.5 hours) = 66 mile/hour

Your linear equation is ...

y = 66x
