Question

When the lid is left off an ink bottle, the ink evaporates at a rate of
2.5 x 10cm/s. A full bottle contains
${36}^{3}$
cm of ink. How long, to
the nearest day, will it take for all the ink to evaporate?​

Answer 1

Given : When the lid is left off an ink bottle, the ink evaporates at a rate of 2.5 x 10⁻⁶ cm³/s ,   A full bottle contains 36  cm³    of ink.

To Find : How long, to  the nearest day, will it take for all the ink to evaporate?​

Solution:

Total Ink in bottle   = 36  cm³  

ink evaporates at a rate of  2.5 x 10⁻⁶ cm³/s

Time taken to Evaporate =  36   / 25 x 10⁻⁶   secs

= 36 x 10⁶  /25

I hr = 3600 sec

1 day = 24 hrs

Seconds in a  day = 24 * 3600  

Time in Days  =   36 x 10⁶   / 25 * 24 * 3600

= 10⁴  / 600

= 10²/6

= 100/6

= 50/3

= 16.67

≈ 17 days

it take 17 Days  for all the ink to evaporate?
