Reeling them in. A simple question of maths.

[PeteXXX]

No @Drago not a fishing thread to block!

A question.
If I start cycling the 6.55 miles around Pitsford Reservoir with some friends who ride at 11.8 mph and I'm slightly faster than them at 12.3 mph, how long will it be before I lap them and how far will we have ridden?
And... if I stop at the cafe, 3 miles in, that then extends my ride by ¼ mile, and stop for 10 minutes for a coffee, at what point would I catch them up as they will have overtaken me by then.

Are you going clockwise or anticlockwise - relativity matters

Easy, 27 hours 37minutes and 17 seconds.

Does that include toilet breaks.

 

[Drago]

Pitsford? You'd be robbed before you lapped them.

That's nearly as long as a Sir Ken Dodd Laughter Show.

Anticlockwise. therefore deduct a few seconds.

Assuming equal sized bladders... it levels itself out.

At the cafe? Yep, it's a bit pricey!

Quite a few coppers ride around Pitsford. A fair few live in Brixworth. You ever get round Salcey?

Yep.. I do Salcey. Not quite sure if the same maths work under tree cover or not though

 

[Spiderweb]

My head hurts!

 

[Drago]

Let me know next time you're planning on doing Salcey and I might join in.

Riding straight I make it 24 laps before you lap them .So distance 6.55*24 them 6.55*23 .Time 31.9 mins * 6.55 12hrs 45min approx . But I could be wrong as for the cafe stop I give up my brain hurts
