Driving on the Autobahn in Germany, you have to brake suddenly. Let’s assume that the stopping distance of a car varies directly as the square of the velocity of car when the brakes are applied. A car moving at 85 mph can stop in 367 feet. a. Write an equation that relates the stopping distance to the velocity. b. What is the stopping distance of your car if you were moving at 95 mph?
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.
