Anton and his friend Jose are playing tag. Anton takes off running at a rate of 7.5 miles per hour. One minute later, Jose starts to chase Anton at a rate of 9 miles per hour. How many miles did it take for Jose to catch Anton?

idk

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
