(PLEASE HELP I DONT UNDERSTAND HOW TO DO THE MATH FOR THIS IF YOU COULD PLEASE HELP I'D BE GRATEFUL )) The length of a football field is 100 yards. When you compare geologic time (4.6 billion years) to the length of a football field, you will find that each yard on the field will equal 46 million years, and each 10-yard section will equal 460 million years. Use this information to complete the activity below.
Create a digital model of a football field. Starting at the left and moving forward in time, label the 10-yard lines in years. Using different colors, draw a horizontal line to mark the beginning and end of each of the following periods and eras [note that the years have been rounded up for this activity]:
• Cenozoic era (65 MYA to present)
• Cretaceous period (146‒65 MYA)
• Jurassic period (208‒146 MYA)
• Triassic period (245‒208 MYA)
• Paleozoic era (570‒245 MYA)
• Proterozoic era (2,500‒570 MYA)
• Archean era (3,800‒2,500 MYA)
• Hadean era (4,600‒3,800 MYA)
Thx! @David
I've tried to multiply, divide, subtract, and even add but I keep getting numbers that are incorrect!

hope this helps
To complete this activity, you will need to create a digital model of a football field and label the 10-yard lines in years. Then, using different colors, draw horizontal lines to mark the beginning and end of each of the given periods and eras. Here's how you can do it:
1. Start by creating a digital representation of a football field. You can use a drawing or design software, or even a simple drawing app on your computer or mobile device.
2. Divide the football field into 10-yard sections. Label each section with the corresponding years based on the given information: each yard on the field represents 46 million years.
3. Find the starting and ending years for each period and era as provided in the activity. Round up the years to the nearest whole number for simplicity. Here are the ranges for each period and era:
- Cenozoic era: 65 million years ago (MYA) to present
- Cretaceous period: 146‒65 MYA
- Jurassic period: 208‒146 MYA
- Triassic period: 245‒208 MYA
- Paleozoic era: 570‒245 MYA
- Proterozoic era: 2,500‒570 MYA
- Archean era: 3,800‒2,500 MYA
- Hadean era: 4,600‒3,800 MYA
4. Using different colors or styles, draw horizontal lines to mark the beginning and end of each period and era on your digital football field model. Make sure the lines are evenly spaced based on the yard markings.
5. Add labels for each period and era next to the corresponding horizontal lines to indicate which time frame they represent.
By following these steps, you will have created a digital model of a football field with labeled 10-yard lines representing years, and with horizontal lines marking the beginning and end of each given period and era. This visual representation will help you better understand and visualize the vastness of geologic time.
