English arithmetic problems A clock gains (fast) five seconds every hour.If We adjust it to the correct time, twenty four hours later, it's 5:58?

If we are going to adjust it to the right time after 24 hours, then the clock time is 5:58. So, what is the right time?
Because every hour is 5 seconds faster, then after 24 hours it will be 5 * 24 = 120 seconds = 2 minutes faster. Then the correct time should be 2 minutes slower than the clock time, that is 5:56
