The answer is:
4x+2y=11} 4x+2y=11} x=2-2y
x-2=-2y } x+2y=2 } x=2-2(-3/6)
x=2-(-6/6)
4(2-2y)+2y=11 x=2-(-1)
8-8y+2y=11 x=3
8-6y=11
-6y=11-8
-6y=3/-6
y=-3/6=-1/2

So for my opinion the solution is A.(3,-1/2)

Given as :

Time for Janelle to spend on training = 5 hours

The running speed of Janelle = 9 mph

The walking back with 3 mph

Let The distance for running and walking is same i.e D miles

SO, Time = $\frac{Distance}{Speed}$

∴ 5 = $\frac{D}{9}$ + $\frac{D}{3}$

Or, 5 × 9 = D + 3 D

Or, 45 = 4 D

∴ D = $\frac{45}{4}$ = 11.25 miles

Hence The distance cover by him walking back is 11.25 miles Answer
