Answer 2

In context to question asked,

We have to determine the ratio of 45 minutes to 1 Hr 30 minutes.

As we know that,

Ratio of two or more quantities are only determined if their units are same.

So, converting 1 Hr 30 minutes into minutes.

As we know that,

1 Hr = 60 minutes.

So, 1 Hr 30 min. = 60 min + 30 min. = 90 minutes

So, the ratio of 45 minutes to 90 minutes will be,

$=\frac{45}{90} = \frac{1}{2}$

Hence, the ratio of 45 minutes to 1 Hr 30 minutes will be 1:2

Hence, Option C is correct.
