I've finished 13 part a but I can't understand the solution for 13 part b
Will someone please help explain to me where did 5 come from in the sequence?

. So to run one kilometre takes 1/12 hrs or 60/12 minutes. 60/12 = 5.

Re: c2 help with geometric sequencesthank you for trying to help me, however, i'm still a bit confused because even before the whole thing has been converted to minutes.. '5' was already there.. i still don't know where it came from..i'm referring to question part b and i'm sorry for posting the wrong set of solutions earlier which might have caused the confusion..(Original post by ghostwalker)

Re: c2 help with geometric sequencesThe first line of the solution to part b) is in minutes, and the 5 is the length of time, in minutes, it took to run each of the first 15 km.(Original post by desertautumn)

This is multiplied by 1.2 to get the time for the 16th km, etc. -
