this is an algebra systems problem?
Okay, this is a system problem so it needs to equations to solve a.) and b.)
okay, i don't get this problem AT ALL!!
Suppose you are flying an ultralight aircraft to a nearby town 18 miles away. With a tail wind, the trip takes 1/3 hour. Your return flight with a head wind takes 3/5 hour.
a.) Find the average airspeed of the ultralight aircraft.
b.) Find the average windspeed.
And i checked in the back of the book and the answers are: a.) 42 mi/h and b.) 12 mi/h. The problem is that i have NO CLUE how you get those answers!!
Does anyone know how to set up the equations?
Comments
d = r x t
Let rave be the average airspeed of the aircraft
Let rwind be the wind speed
(rave+rwind) x 1/3 = 18
(rave-rwind) x 3/5 = 18
Two equations with two unknowns. Now solve.
Bozo
d=rt
rate is the airspeed plus or minus the tailwind depending on direction.
