To calculate the time it takes for the sound to reach town Y, we need to consider the distance between the cannon and town Y, as well as the velocity of sound in air.
Given: Distance from cannon to town Y (x): 4.95 km = 4950 meters Velocity of sound in air (v): 330 m/s
We can use the formula:
time = distance / velocity
Plugging in the values, we have:
time = 4950 meters / 330 m/s
Calculating the result:
time = 15 seconds
Therefore, it will take approximately 15 seconds for the sound from the cannon to reach town Y, which is 4.95 km away.
