Answer:

8.5 h

Step-by-step explanation:

On the trip to the lake:

d=rt

216 = 48*t

Divide by 48

216/48 = 48t/48

4.5 =t

On the trip from the lake:

d=rt

216 = 54*t

Divide by 54

216/54 = 54t/54

4 =t


The total time spent driving is the time to and the time from

total time = 4.5 +4

                = 8.5 hours
