Question

The number of breaks needed during a 4 1/2-mile hike with breaks at specified intervals can be determined. A bar model representation is required.

Answer 1

To determine the number of breaks needed during a 4 1/2-mile hike with breaks at specified intervals, you can use a bar model representation. The bar model helps visualize the distance and breaks taken, making it easier to determine the number of breaks required.

Step-by-step explanation:

A bar model representation can be used to determine the number of breaks needed during a 4 1/2-mile hike with breaks at specified intervals. The bar model will help visualize the distance covered during the hike and the breaks taken. Here's how you can create a bar model:

1. Draw a long bar to represent the total distance of the hike, which is 4 1/2 miles.
2. Divide the bar into sections to represent the specified intervals where breaks are taken.
3. Count the number of sections to determine the number of breaks needed.

For example, if breaks are taken every 1/2 mile, you would divide the bar into 9 equal sections (4 1/2 / 1/2 = 9). Therefore, 9 breaks would be needed during the hike.
