Anton's family drove 216 mi to the lake averaging 48 mi/hmi/h . on the return trip home they averaged 54 mi/hmi/h . what was the total time that anton's family spent driving to and from the lake? 8.0 h 8.5 h 9.0 h 9.5 h

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

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
