我刚看到前面兄弟的代码AC了，测试了一下好像不太对

from math import *
l = input().split(' ')
s = int(l[0])
v = int(l[1])
t = ceil(s / v + 10)
h = floor(t / 60)
m = t % 60
hour = 7 - h
mi = 60 - m
if hour < 0:
    hour += 24
if hour < 10:
    hour = '0' + str(hour)
else:
    hour = str(hour)
if mi < 10:
    mi = ':0' + str(mi)
else:
    mi = ':' + str(mi)
print(hour + mi)

题目代号 P5707 【深基2.例12】上学迟到

如果输入100 2 会出来06:60 应该是07:00吧
