Question 1085264
He already covered 2 yojanas and he needs to
cover 80 yojanas, so he he has 78 to go
------------------------------------------
If it is a 7 day week, he used up 1 days, so he
has 6 days left
------------------------------------------
His rate of travel must now be:
{{{ 78/6 = 13 }}} 
13 yojanas/day
--------------------
Definitely get a 2nd opinion on this.
I could easily read this incorrectly.
