Simultaneously 25481

When and where will two trains that run simultaneously from stations A and B at a distance of 60 km meet if the train from station A ran at 70 km / h and the train from station B at 50 km / h?

Correct answer:

t =  0.5 h
s1 =  35 km

Step-by-step explanation:

v1=70 km/h v2=50 km/h s=60 km  s=v1 t+v2 t 60=70 t+50 t  120t=60  t=12060=0.5  t=21=0.5=0.5 h
s1=v1 t=70 0.5=35 km
