Answer:
- plane: 530 mi/h
- wind: 40 mi/h
Step-by-step explanation:
Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...
speed = distance/time
p +w = (2565 mi)/(4.5 h) = 570 mi/h
p -w = (2205 mi)/(4.5 h) = 490 mi/h
Adding these speeds, we get ...
(p +w) +(p -w) = (570) +(490) mi/h
2p = 1060 mi/h
p = 530 mi/h
Then the speed of the wind is ...
w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h
The plane's speed is 530 mi/h; the wind speed is 40 mi/h.
The answer to the question they gave you is D
Answer: 1 over 2 (1/2)
Simplify 2 over 8 to get 1 over 4. Now you have 1 over 4 divided by 1 over 2. Whenever you divide with fractions you flip the fraction and multiply . So it becomes 1 over 4 multiplied by 2 over 1.
2/8 (divided by) 1/2
1/4 (divided by) 1/2
1/4 x 2/1
= 1/2
Answer:
M = 1.5
Step-by-step explanation:
First, apply the distributive property to the problem. For this, you will multiply 4 x m, then 4 x 3.
Now, your problem looks like
4m + 12 = 18
Next, you need to get the variable isolated. For this, you need to subtract 12 from both sides.
Now, your problem looks like
4m = 6
Next, you can divide both sides by the non-constant term, which is 4m, so divide by 4.
Now, your problem looks like
M = 1.5
