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%28T%29+, lets replace the letters with the numbers we know
.
+D+=+R%28T%29+ = +256+=+R%284%29+, rearranging, +256+=+R%284%29+ = +R%284%29+=+256+
.
+R%284%29+=+256+ = +%284%29R+=+256+ = +4R+=+256+, to find "R" we will divide each side by "4"
.
+4R+=+256+ = +4R%2F4+=+256%2F4+ = +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%2864%29+=+256+ = ++256+=+256+ (True)
.
Janet was traveling +64+ kilometers per hour, which is your answer
.
Hope I helped, Levi
