The Bible does not really say how long the Israelites walked. A reasonably direct route from the Gulf of Suez to the eastern banks of the River Jordan would be around four or five hundred kilometres. During a period of forty years, and with the needs of around two and a half million people to cater for at any one time, the Israelites would presumably choose to settle in one place and build a semi-permanent city until it was time to move on. Taking a meandering course over the forty years, the Israelites could easily have covered a thousand kilometres.
On the other hand, most biblical scholars say that this is not what really happened. Israel Finkelstein says that over 90 per cent of scholars do not really believe the Exodus from Egypt ever took place. The Israelites never spent forty years in the wilderness.
That depends on the day. Some days were walking days, others were
camping days (Numbers ch.9), and there were places where they stayed for years.
We don't know, because it was a convoluted route.

Forty years (Numbers ch.14)
The book of exodus tells us about the wandering for 40 years.
Deuteronomy 29:4, "I have led you in the wilderness for forty years".
According to the Old Testament, the Israelites (the ancestors of today's Jews) wandered the wilderness (often mistranslated as desert) for 40 years. There is currently no archaeological evidence to support the claim that this event actually happened historically (see also the attached Related Link.).
The trip could have been done in a month.
They journeyed and encamped in the wilderness for forty years (Numbers ch.14), at the guidance of God (Numbers ch.9).
Because of the incident of the spies. See Numbers ch.13-14.
Forty years.
The birds that the Israelites ate (Exodus ch.16, Numbers ch.11) is translated as quail. They ate the quail for two brief periods, not for the whole forty years.
It took 40 years for the Israelites to travel from Egypt to Canaan. Had there been no delays, most could have made the trip in 11 days (Deuteronomy 1). The main delay is explained in Numbers ch.13 and 14.
It is estimated that approximately 2 million Israelites died in the wilderness during the 40 years of wandering before reaching the Promised Land.
