The total distance = 80m................ Given
There are 8 equally spaced hurdles ............ Given
Required is to find the space between the hurdles
The first hurdle is 12m from the start line
and
The last hurdle is 15.5m from the finishing line
Total distance left = 80 - 12 -15.5 = 52.5 m
To share the distance left equally we divide 52.5 by 8
= 52.5/8 = 6.5625 m
The hurdles are 6.5625m from each other because we divided the remaining space after subtractions equally between them
