Xiao Ming's wall clock is slow every hour. At 8 a.m., Xiao Ming sets the clock at the standard time. At 12 noon, what's the standard time?
Set the standard time X
240：X=58.5：60
X = 246 and 2 / 13
246 and 2 / 13 = 12:6 and 2 / 13 minutes
Xiao Ming's clock is 12 minutes slower than the standard time. If Xiao Ming's clock goes for 2 hours, how many hours does the standard time go?
What does the landlord mean by "slow" here? Is it 12 minutes slow every day? Or is it just 12 minutes slow just like the standard clock?
12 minutes a day, right?
If so:
24:12=2:x
The solution is x = 1 (minutes), and the standard clock goes for 2 hours and 1 minute
