What is four eights of six ninths and one half

420 / 8 = $________ per hour
Sure, I can help you with that!
To write the cost of the grapes as a unit rate, we need to find the cost per pound.
We can do this by dividing the total cost of $7.47 by the number of pounds of grapes, which is 3 pounds.
So, the unit rate for the cost of the grapes is $2.49 per pound.
Now, let's move on to the next question.
To write Carla's family's average speed as a unit rate, we need to find the distance covered per hour.
We can do this by dividing the total distance of 420 miles by the total time of 8 hours.
So, the unit rate for Carla's family's average speed is 52.5 miles per hour.
I hope this helps! Let me know if you need any further assistance.
