Question

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 .

Answer 1

Answer:

Option B is correct.

Total time that Antony's family spent driving to and from the lake = 8.5 hr

Step-by-step explanation:

Using time formula:

$Time = \frac{Distance}{Speed}$

As per the given statement:  Anton's family drove 216 mi to the lake averaging 48 ​ mi/hr ​.On the return trip home they averaged 54 mi/hr

⇒ Anton's family drove total distance = 216 mi

Speed of Antony's family driving to lake = 48 mi/hr

Time taken to driving to lake = $\frac{216}{48} = 4.5 hr$

Now,

Speed of Antony's family driving from lake = 54 mi/hr

Time taken to driving from lake = $\frac{216}{54} = 4 hr$

Total time spent  driving to and from the lake = 4 + 4.5 = 8.5 hr.

therefore, the total time that Antony's family spent driving to and from the lake was, 8.5 hr

Answer 2

(driving to the lake) 216 divided by 48 = 4.5
(driving from the lake) 216 divided by 54 = 4

4.5+4=8.5

They drove a total of 8.5 hours to and from the lake.
