Clock A travels to the right at a speed v = v2/7 c relative to clocks B and C. A

Question

Clock A travels to the right at a speed v = v2/7 c relative to clocks B and C. As A passes B, all clocks read 12:00 (shown in the figure above). These readings could be seen simultaneously by a stationary observer O, midway between B and C, though O would make the observation at some later time. (a) Clock C reads 6:00 as A passes C. What does clock A read?
**I know the hour is 5 and it is PM, I just can not get the minutes correct (b) At what time does observer O see the three clocks read 12:00?

Explanation / Answer

v^2/c^2 = 2/7 r = sqrt(1 - v^2/c^2) = sqrt(5/7) = 0.84515 (a) Clock C reads 6:00 as A passes C. What does clock A read? t = 6 hrs, t' = r*t = 5.071 hrs = 5 hr 4 min answer: 5:04 (b) At what time does observer O see the three clocks read 12:00? at 12:00
