Solution

Distance covered by train = 200 km
Speed of train = 60 km h-1

We know speed = `"Distance" / "Time "`

⇒ 60 = `200/"Time" `              

 

Time = `200/60` = `20/6` `10/3` hours 

        = 3`1/3` hours = 3 h + `1/3` hours 

        = 3 h + `1/3` × 60  min 

        =  3 h + 20 min 

        = 3h 20 min
