<PRE><B>Question 732013</B>
given information 
 310 + 60 = 370 mph speed  with the wind
 310 - 60 - 250 mph speed against the wind
 :
 Let d = dist to LA from point of no return
 Then
 (2553-d) = dist to Honolulu from point of no return
 :
 : Time = dist/speed
 :
 Return to LA= Continue to Honolulu time
d/360 = 2553-d/250

 Cross multiply:
 250d = 360(2553-d)
 :
 250d = 919080 - 360d
 :
 610d  = 919080
 d = 1506.69
 Check solution by finding the distance to LA and calculating the time to both:
 2553-1506.69= = 1046.31 mi Honolulu
 :
 Time to L A: 1506.69/360 = 4.19 hrs
 Time to Honolulu: 1046.31/250 = 4.19 hrs
