Answer:
y = 0.3x (pizza delivery driver)
Explanation:
For pizza delivery driver:
15 pizza deliveries in 50 minutes would be equal to 3 pizza deliveries in 10 minutes, or 0.3 pizza deliveries per minute. So the equation here would be y = 0.3x
For hamburger delivery driver:
1.6 hamburger deliveries in 8 minutes would be equal to 0.2 hamburger deliveries per minute. So the equation here would be y = 0.2x
So the pizza delivery driver's rate is faster.
