If your voice is transmitted by your cellphone at the speed of sound, how long will it take the signals to travel to another celphone that is 100 km away?
With solution please. Thanks!How long will it take the signals to travel to another celphone that is 100 km away?First find the speed of sound and if is in meter per second then convert it into kilometers per second by factor label methord which I already did for you.
speed of sound at sea level = 1聽225.044 kilometers / hour now u have your speed and we have to find the time it takes to travel 100 km, so we will use the equation that speed equals distance over time, now u can solve for time.
V=x/t
t=x/v=100km/1225.044km/hr
=0.0816 hour or 4.9 minutes
