X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.
x + y = 2400/5 = 480 - flying with the wind
adding the 2 equations
2x = 880
x = 440
Speed of the plane with no wind = 440 mph
Answer:
im not entirely sure how to help you
Step-by-step explanation:
can you be more specific?
I don't know the second on but the first is pint
V= W × H × L
81000 = 30 × H × 45
81000 = 1350× H
81000/1350 = 1350/1350× H
H = 60 cm
