Answer 2

As per the data given in the above question.

In the above question, it is given that,

The given data is 51 km in 45 minutes

We have to find how long will it take to cover 221 km​.

Thus, solving for 1 km we get,

$=\frac{45}{51}$

Now time taken to cover 221km is as follow,

$=\frac{45}{51}\times 221\\=195minutes$

Hence the time will be 195minutes.
