Two cars (X and Y) leave in the same direction. The car X leaves with a constant speed of 60 km/h and the car Y leaves with a constant speed of 90 km / h.

In one hour (60 minutes) the car Y can get a distance of 30 kilometers from the X car, in other words, it can get away one kilometer for each 2 minutes.

Read the distance (in km) and calculate how long it takes (in minutes) for the car Y to take this distance in relation to the other car.

 

Input

There is only a single input. No multiple test cases. Input is a integer (example D). D means distance between Car X and Y. Here 0<=D<=10000

 

Output

Print the necessary time followed by the message “ minitues”. N.B: no new line (\n) after printing “minitues”.

 

Sample Input

30

Sample Output

60 minitues
