People are going to tell you about heating or cooling the gas, but
there's only one way to change the volume of a gas: Put it into a
different container !
A gas always expands to fill whatever you keep it in ... doesn't matter
how warm or cold it is. So the only way to make it change its volume
is to put it into a larger or smaller jar.

Answer:
time taken with speed 23 km/h will be 1.8 hours or 1 hour 48 minutes
Explanation:
Given:
Time is inversely proportional to the speed
mathematically,
t ∝ (1/r)
let the proportionality constant be 'k'
thus,
t = k/r
therefore, for case 1
time = 3 hr
speed = 14 km/hr
3 = k/14
also,
for case 2
let the time be = t
r = 23 km/h
thus,
we have
t = k/23
on dividing equation 2 by 1
we get
or
or
t = 1.8 hr = or 1 hour 48 minutes ( 0.8 hours × 60 minutes/hour = 48 minutes)
