How to use the formula for distance, rate (speed), and time to solve problems

Описание к видео How to use the formula for distance, rate (speed), and time to solve problems

An introduction to the formula for distance, constant speed, and time: d = vt (or d = rt if you use r as rate instead of v as velocity). First I explain an easy way to memorize this formula in the form v = d/t, comparing it to the common way to express the speed of cars, such as 55 miles per hour.

Then we solve a few simple problems involving distance, time, and speed using the formula.

This lesson is meant for 7th grade / pre-algebra and onward. Check out also my other pre-algebra videos at http://www.mathmammoth.com/videos/pre...
