An engineer bidding on the asphalting of a 7-kn stretch of road is confronted with the problem of choosing between two possible sites on which to set up the asphalt-mixing machine. At site A, the average hauling distance is 2.5km; the monthly rental would be P10,500 and the cost of installing and dismantling the equipment would be P20,000. At site B, the average hauling distance is 3.25km; the monthly rental would be P3,500 and the cost of installing and dismantling the equipment would be P10,200. The asphalt mix is to be hauled by a sub-contractor at P15.25 per cu. m. per km of haul. At site A, it would be necessary to hire 2 flagmen at P150 each per workday. The job can be completed in 30 weeks or 7 months working 6 days a week. The project requires 16,670 cu. m. of asphalt mix per km of road. Which site should he choose and how much lower would his bid be if he made the better choice?

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.
