Knightmare Runs
As Knightmare stretches for his afternoon run, he notices 12 signs along the trail. There is an equal distance between each sign. He begins waddling ... oops ... I meant he begins running and reaches the 8th sign in 8 seconds.
Altogether, how many seconds have elapsed when he reaches the 12th sign?

He'll never make the distance :)
You didn't say how fast the ambulance is.
heh heh ...
an ambulance crew was alerted as Knightmare laced his never-used-before running shoes.
in 12 secondx!
Assuming his starting point is at the 1st sign, then it will take 12.571428571428571428571428571429 seconds to reach the 12th sign.
(plus whatever time he spent musing back at sign #8)
Hi EB ...exactly right 12.57 secs.
I calculate that theses signs were 18" apart at the most, and it took Knightmare over 12 seconds to fall over, due to air resistance slowing his fall.
assuming he begins at the 1st sign, 12.57 seconds
8th sigh in 8 seconds!wow,it must have been downhill...and i was rolling
Knightmare ... trying to make you look good, man!
I meant K took 4.57 seconds to fall over.
Downhill rolling - I wonder if that could become an Olympic sport. K could go for gold.
I misread the question, and couldn't come up with the answer, as I thought it had taken 7 signs to notice the equidistance, then started running took 8 seconds to go from sign 7 to 8.
I then assumed (mistake) that K had been intermittently walking/running/resting up to sign 7.
W=x
Ru=y
Re=0
Then it started getting complicated and I gave up. That took me 12.57 seconds.
Uh 12 seconds. or he died on the way
