Answer 2

In context to question asked,

We have to determine that what percentage of 3 Hr is 42 minutes.

So, for determining the required percentage we will convert 3 Hr into minutes.

As we know that,

There are 60 minutes in 1 Hr.

So, there will be $=(60\times 3) = 180\:minutes$  into 3 Hr.

So, let x% of 180 minutes is 42 minutes.

So, for determining the percentage we will divide the number by 100.

Hence, we will get,

$x\%\:of\:180=42\\=>\frac{x}{100}\times 180 = 42\\=>x = \frac{42 \times 100}{180}\\=>x =23\frac{1}{3}\%$

Hence, $23\frac{1}{3}\%$ of 3 Hr will be 42 minutes.
