Answer:20mph
Step-by-step explanation:
speed of plane = x mph
Speed of plane with wind = 485 mph
So therefore, speed of wind =
485 - x
Speed of plane against wind = 445 mph
So therefore, speed of wind =
x - 445
So therefore, equating the 2 equations of speed of wind
485 - x = x - 445
Collect like terms
485 + 445 = x + x
930 = 2x
2x = 930
x = 930/2 = 465 mph
Speed of wind = x = 465mph
So we put this value on any of the equations for speed of wind
Speed of wind = x - 445 = 465 - 445
= 20 mph
So therefore, speed of wind = 20mph
Answer:
Therefore, we conclute that the map distance between A and C is 35 m.u..
Step-by-step explanation:
We know that the order of three loci is A B C, and the map distance between A and B is 15 m.u., and the map distance between B and C is 20 m.u. We calculate the map distance between A and C.
Therefore, we get
Therefore, we conclute that the map distance between A and C is 35 m.u..
Answer: The mean height of women in a country ages 20 29
The mean height of women in a country (ages 20-29) is 63.7 inches.
2 times (9+7) is correct.
9 + 7 = 16.
16 multiplied by 2 is 32.
