<h2>Option 1 is correct option .</h2>
Explanation:
The velocity of sound depends upon temperature . The temperature is different at different altitudes .
The velocity of sound has no effect of pressure . Thus at different altitudes , if pressure is different , it makes no difference .
Therefore the speed of sound varies rapidly with altitude , due to variation of temperature .
It also depends on the nature of medium . which also varies with altitude .
Moreover we cannot get distance by dividing time interval with 3 .
That's a reasonable request, but right now, there's no way to do it yet. First, we need all the information that's in the REST of the question . . . the whole part BEFORE where you started copying.
