By inclusion/exclusion,
We have
so that
Now,
and by inclusion/exclusion,
Decompose 
into the union of two disjoint sets:
Since they're disjoint,
From the Venn diagram, we see there are 3 elements unique to 
- by the way, this is the set 
- so 
, and it follows that
Finally, we get for (a)
For (b), we have by inclusion/exclusion that
The number of miles that Jose will have left after resting will be 1 1/8 miles.
Total distance to be covered = 2 3/4 miles
Distance traveled = 1 5/8 miles
Therefore, in order to get the distance that's left for Jose to complete his journey, we've to subtract the distance traveled from the total distance and this will be:
= 2 3/4 - 1 5/8
= 2 6/8 - 1 5/8
= 1 1/8
Therefore, he has 1 1/8 miles left to travel.
