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.
All you have to do is divide 38 divided by 5 which = 7 r 3
I hope this helps.
Have a awesome day. :)
The answer is: "100" .

Explanation:
__________________________
Looking at the ENTIRE EQUATION (all numeric values on BOTH sides of the equation), we can see that the decimal that with the most decimal places goes to the right, to the hundredths place (i.e. two places); so by multiplying the ENTIRE EQUATION (BOTH SIDES—i.e. EACH term on EACH SIDE) by "100", we get rid of ALL the decimals, as follows:
_________________________________________
100* {<span>5.6j – 0.12 = 41.1 j ) ;
</span>↔ (100* 5.6j) – (100 * 0.12) = (100 * 41.1 j );
↔ 560 j – 12 = 4110 j ;
