paul left springfield traveling north at 61mph. two hours later tim left springfield going south at a rate of 65mph. how long will it take after paul left to be 1004 miles apart?

Answer provided by our tutors

To solve, set

 

61(h) + 1004 =65(h-2)

 

where h is the number of hours since paul left

61h +1004 =65h -130

61h + 874 =65h

4h = 874

 

h=218.5

218.5 hours after paul leaves, tim will be 1004 miles past him.
