# What time is it?

What time is it, when there is 4 times less time left until midnight than the time that has elapsed since noon?
What time is it, when one-fifth of the hours that have passed since midnight is equal to one-third of the hours that are missing by 12 o'clock?

Result

a = 14:24 hh:mm
b = 7:30 hh:mm

#### Solution:

a-12 = (24-a)/4

5a = 72

a = 725 = 14.4

Our simple equation calculator calculates it.

b/5 = (12-b)/3

8b = 60

b = 152 = 7.5

Our simple equation calculator calculates it.
