We plan to build six houses at regular intervals in a city of 11.5 kilometers (km). If you build houses at both ends of the city, how many kilometers (km) apart should the houses be?
11.5 6 1 [OP_SUB] [OP_DIV]
var_a = 11.5
var_b = 6
var_c = 1
var_d = var_b - var_c
var_e = var_a / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
