AFTER 40.67 DAYS
DO the work by yours self

1586/39=40.66666666666666666667 days
Khan , I think your units are off
40.6666 .... Hours

The rate is km per hour

1586 km / ( 39 km/1hour)
= 1586 km x (1 hour/ 39 km)
Km drops and your left with hours
Not sure where the days come in except 40 hours is short of 2 days
