Answer: 2/3 hours

Step-by-step explanation:

okay so the speed now is 850, which is 850/340 = 2.5 times the original speed

Since It's 2.5 times the original speed,

2.5x = 5/3

so x = 5/3/2.5 = 2/3

Answer:

The required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

Step-by-step explanation:

We know that for a certain amount of dry gas when the pressure is kept constant it's volume V and temperature T is related by the function,

V = cT -----------------------(1) [where "c" is a constant]

So, in that case rate of change of volume(V) with respect to time (t),

= $\frac {dV}{dt}$

will be equal to ,

$c{\frac{dT}{dt}}$

where $\frac {dT}{dt}$ is equal to rate of change of temperature (T) with respect to time (t) and c is the constant stated before.

So, the required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$
