En el circuito de Montjuic, un ciclista realiza la subida en 7 minutos con una
velocidad de 25 Km/h. Si su perseguidor realiza la subida en 5 minutos. ¿Qué velocidad
lleva?

i dont know sorry

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

i think its 7.6

if so your welcome

the answer is b to that quesiton
