Some examples of unit rates are kilometer per hour (kph), miles per hour (mph), words per minute (wpm), etc. In problems, the symbol “/” may substitute the word “per.” The following are examples of unit rates: ( a ) The car travelled 80 kilometers in 2 hours. The unit rate...
Of course, all of this is silly. Miles per gallon is a useful measure if that is the only fuel that you are putting into your car, because then it gives you an indication of how much it would cost you to drive. But electricity is not free. Probably a better measure would be cents ...
Unit rates are very common in our lives. For example, when we say that we are driving at a speed of6868miles per hour we mean that we travel6868miles in11hour. We would write this rate as6868miles/hour (read6868miles per hour). The common abbreviation for this is6868mph. Note...
From the calculation above, a 10 Hz tire rotation rate would equate to a truck speed of approximately 71 miles per hour. That sounds about right for a truck traveling on the highway!This 10 Hz fundamental frequency is easily distinguished in the freight vibration data; but one can argue it...
Two birds are migrating due north. The first bird flies at a rate of 35 miles per hour. It will eventually migrate on the same path as the second bird, which begins its journey 45 miles directly north of the first bird. The second bird flies at an averag
This lesson demonstrates a few different ways to calculate unit rates. We use them to solve problem such as how many beats per minute, or how many miles per hour. To master this lesson, you must understand how ratios and fractions will help to find the unit rate based off of a higher ...
In mid-2017, Audi announced its new A8 would be fully self-driving up to 40 miles per hour. Nissan is following suit with a full range of driverless vehicles by 2020.DAVID ROGERSMotor age
A simple linear regression model of miles per gallon ({eq}y {/eq}) on number of cylinders ({eq}x {/eq}) was fitted based on a dataset containing information regarding these aspects in {eq}32 {/eq} automobiles. The fitted line that was obtained is {eq}\hat{y} = -2.8758x + ...
Friction head loss (ftH2O per 100 ft pipe) in water pipes can be estimated with the empirical Hazen-Williams equation. The Darcy-Weisbach equation with the Moody diagram is considered to be the most accurate model for estimating frictional head loss for a steady pipe flow. Since the Darcy-...
Whether the vehicle can transport a load at a sustained speed of at least 25 miles per hour It’s irrelevant that a vehicle can transport a greater load off the public highway than it’s permitted to carry on a public highway.
