Against each other

From two points, A and B distant 29 km at the same time started two cars against each other at speeds 82 km/h and 72 km/h. How long do cars meet, and what distance passes each of them?

Correct answer:

t =  11.3 min
s1 =  15.44 km
s2 =  13.56 km

Step-by-step explanation:

s=29 km v1=82 km/h v2=72 km/h  v=v1+v2=82+72=154 km/h  T=vs=154290.1883 h t=T min=T 60  min=0.1883 60  min=11.3 min=11.3 min
s1=v1 T=82 0.1883=15.44 km
s2=v2 T=72 0.1883=13.56 km
