<PRE><B>Question 541064</B>
A plane is traveling from Los Angeles to New York for a total of 2650 miles.
 It will take 5.4 hours to complete the trip after traveling 475 miles.
 How many hours will it take to complete the whole trip?
:
Find the speed of the plane
s = {{{((2650-475))/5.4}}}
s = 402.778 mph
:
Find the time of the whole trip
t = {{{2650/402.778}}}
t = 6.58 hrs
;
:
Check this by finding the time of the 1st 475 mi
{{{475/402.778}}} = 1.18 hrs
Add to the time of the rest of the trip
5.4 + 1.18 = 6.58 hrs</PRE>
