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:

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 = 
Now,
Speed of Antony's family driving from lake = 54 mi/hr
Time taken to driving from lake = 
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:
the second one is your answer
Answer:
52
Step-by-step explanation:
1/4 x 52 equals 13.
Their momentum would be equal. so,
m1v1 = m2v2
0.25 * v1 = 0.05 * 500
v1 = 25 / 0.25
v1 = 100 m/s
In short, Your Answer would be 100 m/s
Hope this helps!
