please help me !! Two friends live 28 miles apart on a straight road. One can bicycle 3 miles per hour faster than the other. They start at the same time and meet after cycling for 2 hours. What rate did each cycle?

OpenStudy (anonymous):

one persons rate we could put as say \(x\) and then the other would be \(x+3\)

OpenStudy (anonymous):

in two hours one has gone \(2x\) miles and the other has gone \(2x+6\) miles

OpenStudy (anonymous):

since they meet at the same place, this tells you that \(2x+2x+6=28\) and you can solve for \(x\)
