Question

a passenger train,running at a speed of 80km/h leaves a railway station 6h after a goods train leaves and overtakes it in 4h. what is the speed of the goods train.​

Answer 1

32 km/h

Step-by-step explanation:

According to the question,

Speed of passenger train = 80 km/h

Time taken by passenger train = 4 h

Let, speed of goods train = v

Time taken by goods train = 6+4 = 10 h

Distance covered by both the trains is same.

Now, by using, Speed = Distance/Time

Distance = Speed × Time

Distance = 80×4 = v×10 ==> v = 32 km/h
