An airplane flys 2750 miles in 5 hours. round to the nearest .100, find unit rat, and mp second

In 5 hours the plane covers 2,750 miles .

What about  in 1 hour?

We form an equation:

5 = 2750

1  =  x

Where x is distance travelled in 1 hour.

Cross multiplying the equation, we get:

5 * x = 2750 * 1

5x = 2750

x = 2750 /5

x = 550.

I hr = 550 miles.

We know 1 hr has 3,600 seconds  and I mile has 1609.34 meters, so:

1* 3,600 = 550 *  1609.34

3,600 seconds  = 885,137 meters.  How about 1 second?

1 second = 885137 / 3,600

1 sec = 245.87 meters.

Therefore The airplane flies at a rate of 245.9 m/s

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer:

a=9
