Mr foster places 11 garden lights along an 80 meter path. Each light is placed an equal distance apart. How far away is the sixth garden light from the second?
80/10 = 8 feet apart
4 * 8 = 32 feet
Math - correction -
The units are meters, not feet.
the equation used is:
distance/(number of things dividing -1)
this works because you have one light at the beginning and one at the end. So you end up with(number of things dividing -1)for the number of parts.
ex: 1 foot with 3 lights, that are equal distance, mean they will be placed .5 , half, a foot away from the nearest light
the second equation is:
(starting position - end position)* distance in each part
Note: the answer will always be positive
