Malik owns a small snowplow company with three private plows. Malik operates one plow during snowstorms, along with employees Jake and Manuel. They need to plow a very large parking lot. When all three of them work together, they can plow the entire lot in 220 minutes. Malik and Jake had worked together once and plowed the entire lot in 310 minutes between the two of them. After one particular storm, all three worked together for 20 minutes, after which Malik had to leave. Jake and Manuel required 320 more minutes to finish the lot. Assuming no loss or gain in efficiency, how long would it take each person to complete the entire job alone? Round final answers to 1 decimal place accuracy. Do not round intermediate steps. Show your complete system of equations in your notes. Use the calculator to solve a matrix. EQUATION NEEDS TO BE IN MATRIX FORM! It would take Malik _____ minutes to plow the lot; It would take Jake ______ minutes to plow the lot; and It would take Manuel ______ minutes to plow the lot.
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.
