Question 34

An ordinary clock in a factory is running slow so that the minute hand passes the hour hand at the usual dial positions ($12$ o’clock, etc.) but only every $69$ minutes. At time and one-half for overtime, the extra pay to which a $\$4.00$-per-hour worker should be entitled after working a normal $8$-hour day by that slow-running clock is:
  1. $\$2.30$
  2. $\$2.60$
  3. $\$2.80$
  4. $\$3.00$
  5. $\$3.30$
