Answer:
V = 160mph
Step-by-step explanation:
We need to start from the formula of speed: V=d/t
We have two travels, with and against the wind, both done in the same time.
Clearing t from the formula, we will have: t=d/V2
450miles/V-35mph (speed of the wind is subtracted)
702miles/V+35mph (speed of the wind is subtracted)
Now, we find V:
450miles/V-35mph = 702miles/V+35
450*V+35 = 702*V-35
450V+15,750 = 702V-24,570
702V-450V = 15,750 + 24,570
252V = 40,320
V = 40,320/252
V = 160mph
Answer:
Hope this will help you. Here you have to use the formula P = 2(l+b)
If the ratio of red to blue pens is 3:1, we can find the amount of blue pens by multiplying by 1/3, to get 21*1/3=7. There are 21 red pens and 7 blue pens, so there are 21+7=28 pens total.
2120 acres* (13/100)= 275.6 acres.
275.6 acres of pine trees still remains today~
