다운로드매니저로 1초당 몇바이트가 전송되는지는 어떻게 구현하나요?

Question

var enqueue: Long = 0
var dm: DownloadManager? = null

thread {
    var downloading = true
    while (downloading) {
        val query = DownloadManager.Query()
        query.setFilterById(downloadId)

        val cursor = downloadManager.query(query)
        if (cursor.moveToFirst()) {
            val bytesDownloaded =
                cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR))
            val bytesTotal =
                cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES))

            if (cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS)) == DownloadManager.STATUS_SUCCESSFUL) {
                downloading = false
            }

            val progress = ((bytesDownloaded * 100L) / bytesTotal).toInt()
            fun DownloadProgress() {}
            runOnUiThread {
                Log.i("printbytesDownloaded", bytesDownloaded.toString())
                Log.i("printishsawantprogress", progress.toString())
                Log.i("printDownloadProgress",toString())
        }

uri 다운하는거 까지는 만들었는데 1초당 몇바이트가 전송되는지까지 구현하고 싶습니다. 어떻게 해야할까요?
