There are 45 streetlights on one side of the road, spaced at 60 meters (m) intervals. What is the distance in kilometers (km) from the first street lamp to the last lamp?
60 1000 [OP_DIV] 45 1 [OP_SUB] [OP_MUL]
var_a = 60
var_b = 1000
var_c = var_a / var_b
var_d = 45
var_e = 1
var_f = var_d - var_e
var_g = var_c * var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
