```python
a,b=map(int,input().split())
if(a%b==0):
c=int(a/b)+10
else:
c=int(a/b)+11
if(c>480):
t=24*60-(c-480)
h=t%60
h1=int(t/60)
else:
t=480-c
h=t%60
h1=int(t/60)
if(h1>10):
if(h>10):
print(str(h1)+':'+str(h))
else:
print(str(h1)+':'+'0'+str(h))
else:
if(h>10):
print('0'+str(h1)+':'+str(h))
else:
print('0'+str(h1)+':'+'0'+str(h))
```

hack数据: `100 1`
期望输出: `06:10`
实际输出: `06:010`
解决方法：`h>10`全部改成`h>=10`，否则`10`会补一个零挂掉
