Question

Darren ate 1/3 of an 18-inch-pizza in 5/6 of a minute. What would be his unit rate of pizzas per minute eaten?

Answer 1

he would have eaten 0.12 inches of pizza every second: 

6 inches in 50 seconds. 

Now divide 6 by 50 to get how many pieces of pizza per second which would be 0.12 inches per second.
