Answer:
4.8 hours
Step-by-step explanation:
The speed of the boy is 2.5 miles per hour. Speed is defined as distance over time:
[tex]V=d/t[/tex]
We have the speed and the distance and therefore we can work out the time in hours:
[tex]2.5=12/t[/tex]
[tex]t=12/2.5=4.8[/tex]
The boy took 4.8 hours to reach the house
