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 ...
Truck Speed from Tire Rotation Rate Now we need to understand what a rotation in Hertz equates to in relation to truck speed in miles per hour. Hertz is rotations per second, so first we need to determine the number of rotations per hour by multiplying by 3600. Now we need to calculate...
You are confusing yourself by talking about "kilowatts/sec" and "kilowatts/min"; those terms make no more sense than something like "miles per hour per day". Power, measured in watts, is not an amount of work but the rate at which that work is delivered: one Joule of work per...
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. Meanwhile, robots are performing surgery, computers are diagnosing cancer, and in late 2017, the news media reported on ...
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...
Scott, let me start by saying YOU ARE THE MAN. Not only did you answer the question, you broke it down so I could understand how each piece relates to the puzzle. This is beyond what I expected, and definately put me miles down the road. I don't know where you work, but you des...

traveled at an average ground speed of 180 miles per hour. If the operator is also interested in the distance between Santa Barbara and Victorville, he may note at a glance by the graduations on the base member that the distance is approximately 143 miles....
