Step-by-step explanation:
Answer:
The speed of the plane with no wind is 378 miles per hour.
Step-by-step explanation:
Since at maximum speed, an airplane travels 1680 miles against the wind in 5 hours, and flying with the wind. the plane can travel the same distance in 4 hours, to determine what is the speed of the plane with no wind, the following calculation must be performed:
Against the wind = 1680/5 = 336
With the wind = 1680/4 = 420
420 - ((420 - 336) / 2) = X
420 - 42 = X
378 = X
Therefore, the speed of the plane with no wind is 378 miles per hour.
They bowled for 3 hours and spent $7.
(I have no Idea how to make a graph on this website, so I can't help you there, sorry)
Let x = number of hours
Tucker: 2x+1
Blanca: x+4
2x+1 = x+4
x=3
For the graphs your lines should have equations like this:
y= 2x+1
y=x+4
The point of intersection of these lines should be at point (3,7)
Answer: 13 ≥ v - 1
Step-by-step explanation: The equation above represents the situation; Thirteen is at least the difference of a number v and 1
