Question

enn is flying in a plane. there is a proportional relationship between the distance she flies (in miles), d, and the amount of time she has been flying (in hours), h. the distance the airplane has flown is given by the equation d = 520h. what is the constant of proportionality? miles per hour

Explanation:

Step1: Recall proportional relationship formula

A proportional relationship is in the form \( y = kx \), where \( k \) is the constant of proportionality.

Step2: Identify \( k \) in given equation

Given \( d = 520h \), comparing with \( y = kx \) (here \( y = d \), \( x = h \)), the constant \( k \) is 520.

Answer:

520
