Running is a popular sport in the United States. Equipment needs are minimal and runners can train anywhere. Running has excellent health benefits. A data set about various races across the US in 2019-2020 was constructed. A small portion of that data set is displayed below: Race Name Surface Distance (miles) Winning Time Cash Prize State Rating AJC Peachtree Road Race 10K road 6.2 28:49 yes GA 5 stars Jimmy The Greek's Frozen 4 Miler road 4 21:37 yes ME 3 stars Beer and Bagel Off Road trail 4 24:03 no PA 3 stars Meadows and Trails 5K trail 3.1 21:13 no NY 2 stars K9S United 9K road 5.59 32:46 no FL 3 stars Grey Towers 8K Run road 4.97 32:38 no PA 2 stars ... ... ... ... ... ... ...

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
