RT=D for rate, time, distance.
Assign some variables, and set a data table.

The description is slightly confusing, but Meri seems to start late. Fifteen minutes is hour. Meri seems to run for less time than Cate.

________________speed_________time__________distance
Cate____________4_____________t+1/4_________4(t+1/4)=d
Meri____________6______________t____________6t=d

d is distance for which Cate and Meri match, or for which Meri catches up with Cate. t is time in hours that Meri runs when she catches up with Cate.

Both distances are the same.
.

One might assume that you had some mistakes in analyzing the problem and developing a correct equation allowing the solution. You would solve the shown equation for t.
