Given : Alexa is planning to drive across the United States in her car
She started filling out the table showing how far she can travel for each gallon of gas that she uses.
Gallons Miles
2 56
4 a
b 168
10 c
To Find : the missing values a , b , c and constant of proportionality
Solution:
constant of proportionality of x miles per gallon
=> Miles = x * gallons
Gallons = 2
=> Mile s= 2 * x = 56
=> x = 28
Gallons = 4
=> Mile s= 4 * 28 = 112 = a
Gallons = b
=> Mile s= b * 28 = 168
=> b = 7
Gallons = 10
=> Mile s= 10 * 28 = 280 = c
Gallons Miles
2 56
4 a =112
b=7 168
10 c=280
constant of proportionality = 28
a = 112
b = 7
c = 280
