Answer:
- airplane: 225 mph
- wind: 45 mph
Step-by-step explanation:
The average speed with the wind is (540 mi)/(2 h) = 270 mi/h.
The average speed against the wind is (540 mi)/(3 h) = 180 mi/h.
Let a and w represent the speeds of the airplane and wind, respectively.
a + w = 270 . . . . speed with the wind
a - w = 180 . . . . speed against the wind
2a = 450 . . . . . . sum of the two equations
a = 225 . . . . . . divide by 2
w = a -180 = 45
The speed of the airplane is 225 miles per hour; the speed of the wind is 45 miles per hour.
<span>(1 + 1) ÷ 2 + 1 <span>answer is 2.
Here are the steps.
1. Reduce 1 + 1 to 2 ( 2 </span>÷ 2 + 1).
2. Reduce 2 ÷ 2 to 1 ( 1 + 1).
3. So finally the answer is 2.</span>
Your 71,1482 doesn't make sense. But regardless,
let x = the other car's cost.
You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.
You can do $38,295 + c = $71,1482.
Or $71,1482 - $38,295 = c.
