If Chanhui walks 0.75 meters (m) per step and walks 70 steps straight for 1 minute, how many meters (m) does Chanhui's location after 13 minutes differ from his current location?
0.75 70 [OP_MUL] 13 [OP_MUL]
var_a = 0.75
var_b = 70
var_c = var_a * var_b
var_d = 13
var_e = var_c * var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
