but ram sitting in a car approaching the place of firing hears the second fire 5 minute 32 second after the first firing.
what is the speed of the car, if speed of sound is 332m/sec?
:
Find the change in distance in 28 seconds (6min - 5m32sec)
28 * 332 = 9296 meters
Find the car speed if it takes 5 min 32 sec to travel 9296 meters
Change 5 min 32 sec to 5.5333 min = 1680 meter/min
Convert to km/hr = 100.8 km/hr
