To get in shape for a marathon, Shelby started running around the block a few times each morning.

What is -inform?

To calculate the distance Shelby is running each morning, we need to know the distance around the block. Let's assume the block is a regular square shape.

To find the distance around the block, Shelby can use a measuring tool like a measuring wheel or a GPS device with distance tracking.

Alternatively, Shelby can measure the length of one side of the block using a measuring tape, and then multiply it by 4 (since all sides of a square are equal in length) to get the distance around the block.

Once Shelby knows the distance around the block, they can multiply it by the number of times they run around the block. For example, if the distance around the block is 0.5 miles and Shelby runs around it 3 times, the total distance covered would be 0.5 * 3 = 1.5 miles.

Keep in mind that it's important to gradually increase the distance and intensity of the runs to prepare for a marathon. Consulting with a fitness professional or following a training plan specifically designed for marathon preparation is also highly recommended.
