Question

Convert the following a. 5 cm into m c. 172800 s into day

Answer 1

a)$\large\fcolorbox{red}{cyan}{0.05 m}$

b)$\fcolorbox{red}{cyan}{2 days}$

Explanation:

A)Convert 5 cm into m

We Know That 1 m = 100 cm

$100 cm = 1 m \\ => 1 cm = \frac{1}{100} \\ => 5 cm = \frac{1}{100} \times 5 \\ => \frac{1}{20} \\ => \boxed{0.05 m}$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

B)Convert 172800 s into days

• 1 day => 24 hours
• 24 hours => 1440 min
• 1440 min = 86400 sec

Therefore 1 day = 86400 s

$86400 sec = 1 day \\ => 1 sec = \frac{1}{86400} day \\ => 172800 sec = \frac{1}{86400}\times{172800} \\ => \boxed{2 days}$

Hope it helped
