Simultaneously 81403

Cars left two places 520 km apart simultaneously at speeds of 30 km/h and 50 km/h. Where and when will they meet?

Correct answer:

s1 =  195 km
s2 =  325 km
t =  6.5 h

Step-by-step explanation:

s=520 km v1=30 km/h v2=50 km/h  v=v1+v2=30+50=80 km/h  t=s/v=520/80=213=6.5 h  s1=v1 t=30 6.5=195 km
s2=v2 t=50 6.5=325 km
