Question

A train runs at 45 km/h how far does it go in 6 seconds ?

Answer 1

i think its just 450 meters or 45.0 metres

Answer 2

speed of a train => 45km/hour ,

seconds in 1 hour => 60*60 => 3600 secs

therefore,

train travels 45km in 3600 seconds

in 1 second it travels => (45/3600) km

in 6 seconds it travels => (45/3600) * 6 => 45/600 => 0.075km or 75 meters
