Jean drove 65 miles per hour for a total of 455 miles on a trip. She used the equation below to calculate the time, t, it would take her to complete the trip.
What is the constant of proportionality in the equation?
The equation is not provided in the question. Please provide the equation so that I can determine the constant of proportionality.
To calculate the time it would take Jean to complete the trip, we need to find the constant of proportionality in the equation.
The equation used to calculate the time is: distance = speed × time, where distance is 455 miles and speed is 65 miles per hour.
We can rewrite the equation as: time = distance / speed.
By substituting the values, we get: time = 455 / 65.
Calculating the value gives us: time = 7.
Therefore, the constant of proportionality in the equation is 7.
