4. 15) Two jets have a cruising speed of 450 km/h without wind. The first plane flies
for 6 hours with a tailwind. The second plane flied for 8 hours in the opposite
direction against a headwind. The second plane flies 100 km more than the first plane.
Determine two equations that could be used to solve for the wind speed, w , and
the distance travelled by the first plane, d . Just the equations are fine (save time).
Do NOT solve w and d .
Answer:
(450 )(6)
100 (450 )(8)
d w
d w
