if distance is 3200 km a train covers in 6 hours 40 min what I'd speed of train​

Answer 1

Answer:

480km/hr.

Step-by-step explanation:

(60×6)+40=400min.

in 400min the train cover the distance of 3200km

in 1min the train cover the distance of 3200/400km=8km

so in 60min the train cover the distance of 8×60km=480km

60min is also 1hr so the ans is 480km per hr...
