Answer:
- plane: 550 mph
- wind: 50 mph
Step-by-step explanation:
If p and w represent the speeds of the plane and wind, respectively, the speed into the wind is ...
p - w = (3000 mi)/(6 h) = 500 mi/h
And, the speed with the wind is ...
p + w = (3000 mi)/(5 h) = 600 mi/h
Adding these two equations gives us ...
2p = 1100 mi/h
p = 550 mi/h . . . . . . . divide by 2
Then the wind speed is ...
w = 600 mi/h - p = (600 -550) mi/h
w = 50 mi/h
The rate of the plane in still air is 550 mi/h; the rate of the wind is 50 mi/h.
Answer:56.7%
Step-by-step explanation:17% of 30
I'm not completely sure which way they would like for you to do it
but anyways
3 to 15 is a times 5
so 5 times 5 is 25
so a possible width can be 25
as in 15 by 25
or
5 to 15 is times 3
so 3 times 3 is 9
so a possible width can be 9
as in 15 by 9
I personally think 25 inches wide would be the better answer
