(b)
To determine
To calculate: The value of the proportionality constant k to two decimal places and write the equation of variation if the distance between the two cities Los Angeles and San Francisco is 420 miles and the average number of daily calls between the two respective cities are 326,000.
(c)
To determine
To calculate: The average number of daily phone calls between Memphis and New Orleans. If the distance between the two cities is 400 miles and the number of phone calls between two cities C and the calls varies jointly as the product of the cities population and in the inverse direction as the square of the distance d among the cities.
