Imagine you are asked to find the height of a very tall stadium light pole that needs to be replaced at the local high school football field. The problem is that the pole is so old that there is no record of its height. Describe a way that you could figure out the height of the pole with out measuring it directly. (You do not have access to a crane or a lift that will allow you to drop a measuring tape from the top. You need to come up with a way to find the height of the pole without actually measuring the pole itself).
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.
