Answer:

1

Step-by-step explanation:

Distance = speed × time

xy

(X+6)(y-4)=xy

xy-4x+6y-24=xy

xy-xy-4x+6y =24

-4x+6y=24

2x-3y=-12----(1)

so,(x-6)(y+6)=xy

xy+6x-6y=36

6x-6y=36

divided by6=>x-y=6---(2)

2x-2y=12

solve 1 and 2

2x-3y=-12

2x-2y=12

_________

-y=-24

y=24

y=24 in eq 1

2x-3(24)=-12

2x-72=-12

2x=-12+72

2x=60

X=60/2

X=30

speed of the train = 30km/hr

time taken by train=24 hours

xy=30×24=720 km

2x-3y=-12

2(30)-3(24)=-12

60-72=-12

-12=-12 (get cancelled )

==>1 is the final answer
