Convert minutes in seconds

6*60+35+3*60+20
360+35+180+20= 595

Divide by 3600 to convert seconds in to hours

$$\frac{595}{3600}$$~$$\frac{600}{3600}$$~$$\frac{1}{6}$$~17%

B. 17%

D. 10%
E. 6%

Add minutes: (6+3) = 9 minutes
Add seconds: (30+25) = 55 seconds $$\approx{1}$$ minute

(9 + 1) = 10 minutes
1 hour = 60 minutes

$$\frac{10}{60}=\frac{1}{6}*100 = (.167 * 100) = 16.7$$ %

$$\frac{( 6*60 + 35 ) + ( 3*60 + 20 )}{60*60}*100$$

= $$\frac{395 + 200}{3600}*100$$

= 16.53%

~ 17 % answer will be (B)
