C) $0.14, $0.25, 24 miles per hour, 4 yards per second
D) $0.14, $0.25, 24 miles in 6 hours, 4 yards in 15 seconds

Answer 1

The cost per ounce is $0.14 for the first item and $0.25 for the second item. The rate of travel is found to be 24 miles per hour, and 4 yards per second. Thus, the correct answer is option C.

Step-by-step explanation:

Comparing the cost per ounce, the speed per hour, and the distance per time of different scenarios requires a systematic approach to convert the information given into comparable units.

To determine the cost per ounce for the items listed:

1. $1.12 for 8 ounces: To find the cost per ounce, divide the total cost by the number of ounces: $1.12 ÷ 8 ounces = $0.14 per ounce.

2. $4.90 for 20 ounces: Using the same method, $4.90 ÷ 20 ounces = $0.245 per ounce, which rounds off to $0.25 per ounce.

To find the rate of travel:

1. 144 miles in 6 hours: Divide the distance by the time to find the speed: 144 miles ÷ 6 hours = 24 miles per hour.

2. 60 yards in 15 seconds: To find the speed, divide the distance by the time: 60 yards ÷ 15 seconds = 4 yards per second, which is 4 yards per second.

By analyzing each scenario, we can conclude that the correct answers are $0.14, $0.25, 24 miles per hour, and 4 yards per second, which corresponds to option C.
