----
"Given" DATA:
distance = a miles; time = b hrs ; rate = d/t = a/b mph
-----
Problem Procedure
distance = 1000 ; rate = (a/b)+c mph :
----
New time:
time = distance over new rate = 1000b/(a+bc) hours

-------------
His rate for the 1st a miles is a/b
His new rate is (a/b) + c = (a + bc)/c
----------------
To go 1000 miles
t = d/r = 1000/(a+bc)/c
= 1000c/(a+bc) hours
