Question

A Train Cross a pole in
15 seconds. If the train
is 120 meters long find
it's speed in km/hr

​

Answer 1

Answer:

28.8km/hr

Step-by-step explanation:

Since, train had crossed the pole so distance covered by train to cross the pole will be equal to its own length i.e.120 mt

now,

Distance covered by train =length of train=120 meter

Time taken=15 sec

as we know,

speed=distance/time

speed=120/15=8 meter/sec

in km/hr

8*18/5=144/5=28.8km/hr
