Question

a) A train is running at a speed of 90 km/h. In how much time, will it cross two stations7.5 km apart?

Answer 1

Time taken to cross two strains 7.5 km apart = distance/Speed

= 75/900 = 0.0833 hours = 0.0833*3600= 299.88 second

By rounding off 299.88=300 seconds=5 minutes

OR

Time taken to cross the two stations

= distance/Speed

=7.5/90=75/900=1/12 hours=5 minutes
