 The length of a rectangle is 5 cm more than the three times the
width. The perimeter of the rectangle is 54. Find all dimensions
of the rectangle.
L=5+3w
54=2l+2w
54=2(5+3w) +2w
54= 8w+10
W=11/2
So the length of the rectangle is 43/2 cm and the width is 11/2 cm.

 A passenger jet took three hours to fly 1800 miles with
the wind pushing the plane forward. The return trip
against the wind took four hours. What was the jet's
speed in still air and the wind's speed?
(speed)(time)=Distance
with the jetstream: (p + w)(3) = 1800
against the jetstream: (p – w)(4) = 1800
p + w = 600
p – w = 450
Then, by adding down, 2p = 1050 so p = 525, and w must then be 75.
The jet's speed was 525 mph and the windspeed was 75 mph.
