There are three main types of average problems commonly encountered in school algebra: Average (Arithmetic Mean), Weighted Average and Average Speed. The following table gives the formulas for average problems: Weighted Average, Mean, and Average Speed. Scroll down the page for examples and ...
we multiply each number by its weighting factor. The average speed of a body in time is the distance traveled by the body divided by the duration of the interval. In statistics, there are several types of "averages". For example, mean, median and mode. In algebra, here are four kinds...
Using speed and time as data to find the mean:If you travel 85 miles in 1 hour and 20 minutes, what was your average speed?The first thing to do with this problem is to convert the time into minutes – time does not work on the decimal system as there are 60 minutes in an hour ...
