Math 108 Exam 2 All work on this Exam must be the student's own work. 5) (8 points) An airplane travels 1100 miles with the jet stream (with the wind) in the same travel 792 miles against the jet stream (against the wind). If the plane's average speed in still air is 344 miles per hour, what is the average speed of the jet stream receive full credit you must define variables and solve using one or more equations. Inen your answer. Define variable(s): Below is an organizational table if you wish to use it. Distance Rate (Speed) Time Check: Answer 6) (6 points) Let n stand for the number of people involved with building a garage, and let t represent the time to build the garage.Explanation / Answer
distance rate time
with jetstream 1100 344+ x t
against jetstream 792 344-x t
t = 1100 / ( 344 + x )
t = 792 / (344-x )
setting the two equaytions equal
1100 / ( 344 +x ) = 792 / (344-x )
x = 56
average speed of jetstream = 56mph
