Railroad

The railroad runs parallel to the railway. The train travels at 36 km/h on track. In the opposite direction, the motorcycle rides at 90 km/h. The train passes in 3 seconds. How long is a train?

Correct answer:

x =  105 m

Step-by-step explanation:

v1=36/3.6=10 m/s v2=90/3.6=25 m/s t=3 s x=(v1+v2) t=(10+25) 3=105 m
