how long will it take to complete the sweeping?
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.
A road sweeping truck travels at 10mph when sweeping. Suppose a township in the suburbs has 75 miles of road that need sweeping and one sweeping truck. If the utilization of the truck is 80% (accounting for stops and routing to cover all roads), how long will it take to complete the sweeping?
Let the amount of time taken by the truck to sweep the entire town be hours.
The total distance covered by the truck in this time is 75 miles.
The truck only sweeps for 80% of the total time.
Hence, 75 miles is covered only in hours.
The speed of the truck is 10 miles per hour.
