A 1000 milliliter (ml) bucket was filled with water, but there was a hole and water was leaking at a rate of 5 milliliters (ml) per minute. Find the time elapsed when 300 milliliters (ml) of water remain.
1000 300 [OP_SUB] 5 [OP_DIV]
var_a = 1000
var_b = 300
var_c = var_a - var_b
var_d = 5
var_e = var_c / var_d
print(int(var_e))
