Question and answer
A plane flew 1,740 km in 6 hours with a tail wind. On the return trip, going into the wind, the plane flew 570 km in 3 hours. What is the plane's speed if there was no wind? What is the speed of the
wind? Write the system of equations that would be used to solve this problem. A.(r + w)6 = 1740 (r – w)3 = 570 B.(r – w)6 = 1740 (r + w)3 = 570 C.(r + w)3 = 1740 (r – w)6 = 570 D.(r – w)3 = 1740 (r + w)6 = 570
C.(r + w)3 = 1740
