Due to some fault, the driver of a train has to reduce the speed of a train from 200 km/hour to 180 km/hour. Due to the decrease in speed, it takes 60 minutes more than the usual to complete its journey. What is the distance covered by train?

3,600 km
1,800 km
900 km
450 km
1,750 km

Validate

Solution:

Let the distance = d km

d/{180}-d/{200}

= 1 (60 minutes = 1 hour)

d({20-18}/{3600})

= 1
d=

{3600}/2

= 1800 km
