Question 40182
1.
Let x be the distance.
EQUATION:
{{{x/64+x/96=2}}}
{{{6144(x/64)+6144(x/96)=6144(2)}}}
96x+64x=12288
x=76.8
Hence, its is at a distance of 76.8km.


2.Let x be the time for Jogging 
Let y be the time for walking.
Equation1 :
x+y=1
y=1-x (subsitution)

EQuation 2;
5y+9x=6
Subsittufe:
5(1-x)+9x=6
4x=1
x=0.25
1-0.25=0.75
0.75(5)=3.75
Hence, he walks at a distance of 3.75km.
