Some aeronautical engineers are designing an airplane and wish to predict the lift produced by their new wing design. the chord length lc of the wing is 1.12 m, and its planform area a (area viewed from the top when the wing is at zero angle of attack) is 10.7 m2. the prototype is to fly at v

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.

Iwould say the answer is b.  christians believed jesus was the messiah, or savior of man.  because most jews do not believe  in jesus
