1 km = 1000 m = 2 wavelengths in 32 seconds
 
8100 km x 32 seconds/ km = 2592000 seconds = 43200 minutes = 720 hours = 30 days = 1 month

8100x32=259,200 seconds 
 
259,200 seconds/60 =4,320minutes
 
4,320 minutes/60 = 72hours

It's actually 72hours
 
8100 kilometers x32 seconds per kilometer =259,200 seconds
 
259,200seconds x 1 minute/ 60 seconds = 4,320 minutes
 
4,320 minutes x 1 hours/60 minutes=
72 hours
