Question 161041
Hi, Hope I can help,
.
CAN SOMEONE PLEASE HELP ME WITH THIS PROBLEM: 
Solve the problem: 
Janet drove 256 kilometers and the trip took 4 hours. How fast was Janet traveling?
.
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,{{{ D = 256 }}}, {{{ T = 4 }}}, we are trying to find "R"
.
Since {{{ D = R(T) }}}, lets replace the letters with the numbers we know
.
{{{ D = R(T) }}} = {{{ 256 = R(4) }}}, rearranging, {{{ 256 = R(4) }}} = {{{ R(4) = 256 }}}
.
{{{ R(4) = 256 }}} = {{{ (4)R = 256 }}} = {{{ 4R = 256 }}}, to find "R" we will divide each side by "4"
.
{{{ 4R = 256 }}} = {{{ 4R/4 = 256/4 }}} = {{{ R = 64 }}}
.
Janet was traveling {{{ 64 }}} 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
.
{{{ 4R = 256 }}} = {{{ 4(64) = 256 }}} = {{{  256 = 256 }}} (True)
.
Janet was traveling {{{ 64 }}} kilometers per hour, which is your answer 
.
Hope I helped, Levi
