At 5:15 pm, Wendell Wizard turned on a home-made time machine. The machine malfunctioned, it only made the clock on his machine go twice as fast as a normal clock. When later that day Wendell managed to fix this machine, the clock read 7:05 pm. For how many minutes did the clock run at the wrong speed?

The number of minutes [ as shown by the clock ] that the clock ran was   


Two hours less ten minutes =    120 - 10 =   110 minutes


But....the clock ran twice as fast.....so  the actual minutes were  110/2 =   55 minutes
