Answer :
if it takes c minutes to travel from library to mall, and 1/8 to cycle the same distance walking.
So, if the cycle takes x minutes, then the walking takes:
cycle = (1/8) w
x = (1/8)w
w = 8x
hence walking takes 8 times the time used by cycling.
So, if the cycle takes x minutes, then the walking takes:
cycle = (1/8) w
x = (1/8)w
w = 8x
hence walking takes 8 times the time used by cycling.
