dKai = 3r
dJacob = 2(r + 15)
dKai = dJacob + 25
3r = 2(r + 15)
Can you solve for r and answer?

asked • 10/03/17Am I doing this right?
Kai takes off from parking structure 1 at 3:00 PM, driving north. One hour later, Jacob takes off from parking structure 1, too, but he had south, and his speed is 15 mph more than Kai's. At exactly 6:00 PM, Kai has driven 23 miles more than Jacob. How far has each driven?
After using substitution I got 136 miles for both Kai and Jacob and was wondering if that answer is incorrect.
