Average walking speed is 4mph so around 17.5 hrs. but you may have to stop for food & drink,
After three hours the first cyclist is 6 x 3 = 18 miles ahead. The speed of the second cyclict, when he starts, is 4mph relative to the first. So it will take him 18 miles/4mph = 4.5 hours to close the gap.
it depends on your average speed and the type of ground you are walking over. For example on a flat even surface you may achieve about 4mph, in which case 90 miles will take just over 22 hours.
It will take: 20/4 = 5 hours
