raden · Answer

(200+x)/90 = x/80
solve for x, can u ?

raden · Answer

cross product then simplify ...

anonymous · Answer

x=1600 +200=1800

raden · Answer

(200+x)/90 = x/80
90x = 80(200+x)
90x = 16,000 + 80x

subtract by 80x from both sides, will giving us
90x - 80x = 16,000 + 80x - 80x
10x = 16,000

divide by 10 to both sides,
10x/10 = 16,000/10
x = 1,600

thus, the distance between Delhi and Pune = 1,600 km
