Peleton

Cycling race was run at an average speed of 45 km/h. One cyclist lost with defect 8 minutes. How long and how far he must go at speed 51 km/h to catch peleton again?

Correct result:

t =  60 min
s =  51 km

Solution:

s1=s2=s v1(t+8)=v2t v1t+8v1=v2t  t=8v1v2v1=8455145=60 min
s=v2t=5160/60=51 km
