Studentka2010 [4]

Answer:

1) 506.85 minutes

2) 17.33 minutes

3) 23.25 hours

Step-by-step explanation:

1) 16 minutes and 21 seconds

$21\ seconds=\frac{21}{60}\\=0.35\ minutes$

16 minutes and 21 seconds=16.35 minutes

Multiply by 31

$\therefore 16.35\times 31=506.85\ minutes$

2) 537 minutes 20 seconds

$20\ seconds=\frac{20}{60}\\=0.33\ minutes$

537 minutes 20 seconds=537.33 minutes

Divide by 31

$\therefore 537.33\div 31=17.33\ minutes$

3) 999 hours 45 minutes

$45\ minutes=\frac{45}{60}\\=0.75\ hours$

999 hours 45 minutes=999.75 hours

$\therefore 999.75\div 43=23.25\ hours$
