250.5 minutes, or 4.175 hours.

51/45= 1.13333333333

1.13333333333x221= around 250.5 minutes.

I hope this helps! :)

Answer:

195 min (3 hr 15 min)

Explanation:

If a train covers a distance of 51 km in 45 min, then it covers [tex]1.1\bar3[/tex] km per min. To determine how long it will take to cover 221 km, we divide:

[tex]221\div{1.1\bar3=195[/tex]

Therefore, it will take the train 195 min (or 3 hr 15 min) to cover the distance.
