An airplane flies at the average speed
of 750km/h.
What is the duration of 1125km flight?

1 and a 1/2 hours

Basic explanation:

1125/750 equals 1.5. This means that the duration of the flight is 1.5 hrs.

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)
