N2O is nitrous oxide becuase of the nitrogen and oxygen
As the temperature increases the kinetic energy of the molecules increases, if u add more heat you get more kinetic energy.
This question involves the concepts of average speed, distance, and time.
The average speed of the family is "2.5 mi/hr".
<h3>AVERAGE SPEED</h3>
The average speed is defined as the ratio of the total distance covered with the total time taken to cover it.

where,
- s = distance covered = 2.5 miles
- t = total time taken = 1 hour
- v = average speed = ?
Therefore,

v = 2.5 mi/hr
