As 55 min. spaces are covered in 60 min.
=> 60 min. spaces are covered in = 60/55 * 60 = 65 5/11
Now, loss in 64 min. = 65 5/11 - 64 = 16/11 min.
=> Loss in 24 hrs = 16/11 * 1/64 * 24 * 60 = 32 8/11 min.
Hence,loss in a day or 24 hrs = 32 8/11 min.
=> 60 min. spaces are covered in = 60/55 * 60 = 65 5/11
Now, loss in 64 min. = 65 5/11 - 64 = 16/11 min.
=> Loss in 24 hrs = 16/11 * 1/64 * 24 * 60 = 32 8/11 min.
Hence,loss in a day or 24 hrs = 32 8/11 min.
