I've got an equation that has been puzzling me. It's this :
If 5 seconds equals 11.5 cm then how can i find how many seconds is 3.3 cm or 2.5 cm ?
Thanks for your help

First of all, a unit of length can NEVER equal a unit of time.
If however, you are saying that this is a RATIO of time vs length, then set up the ratio as
5 sec : 11.5 cm
5/11.5 sec : 1 cm
10/23 sec : 1 cm
Can you go from here?
I'm a musician and not a mathematician so I'm still a bit puzzled by this. I understand the first two but not the 10/23 sec : 1 cm .
10/23 = 5/11.5. The first fraction is obtained from the second one by multiplying both the nominator and the denominator by 2.
