Question

a train runs at 45 km per hour how far it goes in 6 second​

Answer 1

the train will cover 45km in one hour (ie,. 60 minutes)
so the distance it covered in one second will be 45km÷3600 = 12.5 metres.
so in 6 seconds it will cover 12.5 ×6 = 75 m
hope it helps

Answer 2

THE SPEED OF TRAIN =45 KM/HR

THT MEANS IN 1 HR THE TRAIN TRAVELS 45 KM .

1 HR = 60 MIN

THEREFORE 60/45 = 3/2 OR 1.5

THAT MEANS IN 1 MIN THE TRAIN TRAVELS 1.5 KM

AS 1 KM = 1000 M

so 1.5 Km = 1500 M

I MIN = 60 SEC

THEREFORE 1500/60 = 25

HENCE IN 1 SEC THE TRAIN TRAVELS 25 M

SO IN SIX SEC = 25 ×6 = 150

SO THE TRAIN WILL TRAVEL 150 M IN 6 SEC IF THE SPEED IS 45 KM /HR
