If you were traveling 180 miles at 10 miles per hour (mph), it would take you 18 hours to do it. Create a table and a graph in a spread sheet that shows the time it will take to travel 180 miles if you are traveling 5 mph, 10 mph, 15, mph, etc. all the way up to 180 mph. Attach your sheet with the table and graph here. Finally, answer the following questions. Does increasing from 10 mph to 15 mph have the same effect on the time as increasing from 60 mph to 65 mph? Why is the time difference so different in these two situations? How long would it take if you were traveling 1/2 mph to travel 180 miles? 1/3 mph? 1/4 mph? What would happen if you were traveling 0 mph? How would that be reflected in the graph and the table? Will the table or graph ever reach a time of 0 hours? Why or Why not?

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.
