90 inches or 7.5 feet
Let the length of each step be x,
Distance of each slab is 6x (6 steps = one slab) ...(i)
Length of each step is increased by 3 inches so distance of each step is now x+3
Distance of each slab is 5(x+3) (5 steps = one slab) ... (ii)
Distance of each slab from (i) and (ii) are equal
6x = 5(x+3)
x = 15
Substituting x in (i) or (ii) we get
Distance of each step is 90 inches or 90/12 which is 7.5 feet.
