Question 525643
Henry traveled a miles in b hours and then increases his rate by c miles per hour. How long would it take him to travel 1000 miles at the new rate? 

----
"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
