The time on a digital clock reads 3:33. What is the shortest length of time, in minutes, until all of the digits are again equal to each other?
(A) 71
(B) 60
(C) 142
(D) 222
(E) 111
If the time reads $3: 33$, the next time that all of the digits on the clock are equal to one another is 4:44. Since the amount of time between 3:33 and 4:44 is 1 hour and 11 minutes, the shortest length of time in minutes is $60+11=71$.

ANSWER: (A)
