Hi
jeremy and richard are racing around a track. 
Jeremy does a lap in 5 minutes and richard finishes the same lap in 4 minutes.
 If jeremy is travelling at the speed of 160mph,what is Richards speed{{{highlight(x)}}}(in mph)?
  Note:  D = rt  and distance the same for both
  {{{5*160 = 4*x}}}
      200mph = x
