=================
jar? Must mean jet.
4.5 what? I'll use hours.
-------
h = helicopter's speed
135/h + 1350/5h = 4.5 hours
135/h + 270/h = 4.5 hours
405/h = 4.5
h = 405/4.5 = 90 mi/hr
Jet's speed = 450 mi/hr

           SPEED        TIME       DISTANCE
jet           r        1350/r        1350
Helicopter    r/5       135/(r/5)       135
                       4.5

1350%2Fr%2B675%2Fr=4.5
-
2025%2Fr=4.5
450%2Fr=1
highlight%28r=450%29-----speed of jet
