Question

A train pass to the light stand in 30seconds and it cross to the 300m. Bridge in 1 minute. What is the speed and length of the train

Answer 1

Answer:

5 m/s train speed and 150 meter its length

Explanation:

let L be the length of train and S is the speed of the train

so according to the que.  L/S = 30 sec. (as train pass light stans when it passes that stand by its full length)

now it pass 300 meter bridge in 60 sec.  so speed of train S = 300/60=5m/s

put value of S in L/S=30  we get L(LENGTH)=150 METER
