You want to install 18 street lights equally on both sides of a straight road with a length of 16.4 meters (m). If street lights are installed at the beginning and end of the road, how many meters (m) should the distance between the street lights be?
16.4 18 2 [OP_DIV] 1 [OP_SUB] [OP_DIV]
var_a = 16.4
var_b = 18
var_c = 2
var_d = var_b / var_c
var_e = 1
var_f = var_d - var_e
var_g = var_a / var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
