(A) car travels at 60 kilometers (km) per hour and (B) car travels at 45 kilometers (km) per hour. If 5 hours have passed since starting from the same starting point, how many kilometers (km) is (A) car ahead of (B) car?
60 5 [OP_MUL] 45 5 [OP_MUL] [OP_SUB]
var_a = 60
var_b = 5
var_c = var_a * var_b
var_d = 45
var_e = 5
var_f = var_d * var_e
var_g = var_c - var_f
print(int(var_g))
