Two cyclists, k kilometres apasrt,...

Two cyclists, `k` kilometres apasrt, and stating at the same time, would be togetherin `r` hours if they travelled in the same direction, but would ass each other in `t` hours if they travelled in opposite direction. The ratio of the speed of the faster cyclist to that the slower is `(r+t)/(r-t)` b. `r/(r-t)` c. `(r+t)/r` d. `r/t\ `
