This problem is pretty easy, we will use the distance formula ( D ( distance) = R (rate) * T ( time ) )
.
Janet drove 256 kilometers and the trip took 4 hours. How fast was Janet traveling?
.
Janet travels 256 kilometers, our "D", we are trying to find the "R" (rate), it takes Janet 4 hours, our "T" (Time)
.
In our equation,, , we are trying to find "R"
.
Since , lets replace the letters with the numbers we know
.
= , rearranging, =
.
= = , to find "R" we will divide each side by "4"
.
= =
.
Janet was traveling kilometers per hour ( since our "D" was given in kilometers, Our "T" was given in hours )
.
We can check by replacing "R" with "64" in our equation
.
= = (True)
