Use the Pyth. Theorem to calculate the total distance flown by the plane in 3 1/2 hours:

d = sqrt(750^2 + 750^2) = 750sqrt(2) miles

Now divide this distance by the total time (3 1/2 hours):

750sqrt(2) miles
---------------------- = 303 miles per hour average
    3.5 hours

Which of the following is the solution to the system of equations?
drek231 [11]

Answer:

B (3/4,5/4)

Step-by-step explanation:

y = 2- x

\frac{5}{4}  = 2 -  \frac{3}{4}

y = 3x - 1

\frac{5}{4}  = 3 \times  \frac{3}{4}  - 1

\frac{5}{4}  =  \frac{9}{4}  -  \frac{4}{4}

Hope this helps ^-^
