Micheal and Peter pratise motocross racing. Michael completes one lap in 22s. Peter does 1 lap in 17 seconds. Michael gets a 176 s head start.

a) Write the rules expresing the number of laps completed by each racer in terms of the time since the race began.

b) Who would win the race if it consisted of 30 laps?

So by looking at b) you understand that there has to be someplace in both of the 2 equations that you make from question a) to put (number of laps) so that is obviously one of your variables.

Anyway, if anyone could help with these questions, it would be extremly appreciated. Thank you.

Hello, it is a simple question...
I can't find the way to go to the solution, but I already know it is 1.
I find that 1/(n(n+1)) = 1/n - 1/(n+1) and then?
Any suggestions should be very usefull.
Thanks
