Time unit conversion minutes – UGC NET Question

This option is correct because 1 hour equals 60 minutes. Therefore, 3 hours equals 3 × 60 = 180 minutes. This direct multiplication gives the correct conversion. Hence, three hours correspond to 180 minutes.

Option A:
A value of 120 minutes corresponds to only 2 hours since 120 ÷ 60 = 2. It does not represent 3 hours. Therefore, this option is not correct.

Option B:
Using 180 minutes reflects the correct multiplication of 3 by 60. This matches both the standard unit conversion and everyday experience with time. Thus, this option is accurate.

Option C:
200 minutes would be 3 hours and 20 minutes, which exceeds 3 hours. Since the question asks for exactly three hours, 200 minutes is not correct.

Option D:
240 minutes equal 4 hours, as 240 ÷ 60 = 4. This is more than 3 hours and therefore not the correct conversion.
