.....[1]
As per the statement:
Distance = 22 km
Time = 2 hours.
Substitute the given values in [1] we have;
![\text{Speed} = \frac{22}{2} = 11 km/hr](https://tex.z-dn.net/?f=%5Ctext%7BSpeed%7D%20%3D%20%5Cfrac%7B22%7D%7B2%7D%20%3D%2011%20km%2Fhr)
Therefore, 11 kilometers per hour must you run if you want to run a distance of 22 kilometers in 2 hours
2x + y = x/2 + 1 multiply this by -4:-
-8x - 4y = -2x - 4
4y = 2x Adding:-
-8x = -4
x = 1/2
Substitute in 4y = 2x:-
4y = 2*1/2
y = 1/4
Answer ( 1/2, 1/4)
