D=rt means:

Distance= Rate X Time

Rate affects the equation d=rt like so: rate= Distance / Time

Say you had to find the time it took (in hours) for a car that traveled at a speed of 40 miles per hour to travel 120 miles.

First we define our variables:

The rate (r) at which the car was traveling at is 40 miles per hour.

The distance (d) was 120 miles.

We don't know the time it took, so we'll call that "t" and solve for it now.

Plug the numbers into the equation "d=rt":

(120)=(40)(t)

120=40t

120/40=40t/40 To isolate the variable, divide both sides by 40.

3=t The time is 3 hours.

See? Easy as pie (or easy as pi, as the case may be).

Hope that answers your question-ujhk77
