Walk

Mart takes a walk every day, and his sports watch records the duration and the speed of each constant-speed segment of the walk. After the walk, Mart can download the log file to his computer. From this file, determine the total distance of the walk and the average speed.

The first line contains an integer $N$ ($1 \le N \le 10\,000$). Each of the next $N$ lines contains the following space-separated data about one segment:

• the duration of the segment in minutes and seconds, in the form $M$m$S$s, where $M$ is the integer number of minutes (the minutes part is omitted when the duration is less than one minute) and $S$ is the integer number of seconds (which never exceeds $59$);
• the word kiirusega;
• the speed on this segment, expressed as minutes and seconds per kilometre, in the form $M$m$S$s/km, where $M$ is the integer number of minutes and $S$ is the integer number of seconds (which never exceeds $59$). You may assume that Mart needs at least one minute, but less than one hour, per kilometre.

You may also assume that the total duration of all segments does not exceed $24$ hours.

Print two lines:

• on the first line, the total distance of the walk rounded to the nearest metre, in the form $L$m, where $L$ is the integer number of metres;
• on the second line, the average speed in the form $V$km/h, where $V$ is the average speed in kilometres per hour, rounded to exactly three decimal places.
