Question 1039216: It takes 5 seconds for a clock to strike 5’O clock beginning at 5 O’ clock precisely. If the strikings are uniformly spaced, how long in seconds, does it take to strike 9 O’clock?
a) 9 b) 10 c) 11 d) none of these. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! There are 4 time intervals between strikings
at 5 o'clock:
a ----- b ----- c ----- d ----- e
I count 4 time intervals, so each interval
is sec long
-----------------
At 9 o'clock, there will be 8 time intervals,
and each one is sec long, so it
takes sec to strike 9 o'clock
(b) 10 sec
