Use concatMap instead of flatMap.

Documentation here: https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/core/operators/concatmap.md

var source = Rx.Observable
  .range(1, 10)
  .concatMap(function (x) {
    return Rx.Observable
      .of(x)
      .delay(randomDelay(1000,5000));
  })
 .timeInterval();
