Download Solution PDFGiven:
Speed of the train = 36 km/hr
Distance to be covered = 7/10 km
Formula Used:
Time = Distance / Speed
Calculation:
First, convert the speed to meters per second because the distance is in kilometers and we want the time in seconds.
Speed = 36 km/hr
1 km/hr = 5/18 m/s
⇒ Speed = 36 × 5/18 m/s
⇒ Speed = 10 m/s
Distance = 7/10 km = 700 meters
Time = Distance / Speed
⇒ Time = 700 / 10
⇒ Time = 70 seconds
The train will take 70 seconds to cover a distance of 7/10 of a kilometer.
