Question

Express 30 minutes as a percentage of 3 hours 20 minutes​

Answer 1

Answer:

15%

Step-by-step explanation:

The quantities must be in the same units

Using the conversion

I hour = 60 minutes, then

3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.

Thus

$\frac{30}{200}$ × 100% = $\frac{30}{2}$ = 15%
