An airplane takes 3 hours to travel a distance of 1680 miles with the wind. The return trip was 4 hours against wind. Find the s

nasty-shy [4]

Answer:

Speed of plane in still air: 490 mile/hour

speed of wind: 70 mile/hour

Step-by-step explanation:

still speed = x wind speed = w

with wind: speed = still + wind

(x+w) * 3 = 1680 ...a

against wind: speed = still - wind

(x-w) * 4 = 1680 ...b

b-a ... 4x-4w-3x-3w = 0

x-7w = 0

x = 7w

substitution: (7w+w)*3 = 1680 8w = 560 wind speed (w) = 70

still speed (x) = 7w = 490 mile/hour

Solve for h. -18+7h>12+9h

Evgen [1.6K]

Answer:

$h$

Step-by-step explanation:

$-18+7h>12+9h$

Add 18 to both sides:

$-18+7h+18>12+9h+18$

$7h>9h+30$

Subtract 9h from both sides:

$7h>9h+30$

$-2h>30$

Multiply both sides by -1 and flip the symbol:

$\left(-2h\right)\left(-1\right)$

$2h$

Divide both sides by 2:

$\frac{2h}{2}$

$h$
