Answer: Devon will complete the entire trip in 3 hours 20 minutes

Step-by-step explanation:

Since we have given that

Devon drives
(3)/(4) the distance to his house in
2(1)/(2) hours,

Let the distance be x

According to question, we get


Speed=(Distance)/(Time)\\\\Speed=((3x)/(4))/((5)/(2))\\\\Speed=(6x)/(20)=(3x)/(10)

Now, if he want to travel the entire trip ,

Time taken by Devon is given by


Time=(Distance)/(Speed)\\\\Time=(x)/((3x)/(10))\\\\Time=(10)/(3)\\\\Time=3(1)/(3)* 60\\\\Time=3\ hours\ 20\ minutes

Hence, Devon will complete the entire trip in 3 hours 20 minutes.
