26 minutes
The time between 3 & 6 is 180 minutes. x minutes to 6 is time now. 180-x minutes after 3 o'clock 50 minutes ago was (180-x)-50=130-x 4x=130-x x=26 minutes, 26 to 6= 5:36 is time now
Exactly how many minutes is it before seven o'clock, if 40 minutes ago it was three times as many minutes past two o'clock?
If 2 hours ago it was as long after one o’clock in the afternoon as it was before one o'clock in the morning. What time would it be now?
