Let n = the hours elapsed when the two trains are 660 miles apart.
Let the first train travel east and the second train travel west.
The distance traveled by the first train is
x = (50 mi/h)*(n h) = 50n mi
The distance traveled by the second train is
y = (60 mi/h)*(n h) = 60n h
The distance between the two trains after n hours is
x + y = 50 n + 60n = 110n mi
Because this distance is 660 miles, therefore
110n = 660
n = 6 hours
Answer: 6 hours

Answer:
the first one due to the way up math works
Option B
The volume of sand he will need to fill half of the sandbox is 55.35 cubic feet
<em><u>Solution:</u></em>
<em><u>The volume of rectangular prism is given as:</u></em>

From given,
Area of base = 49.2 square feet
Height = 2.25 feet
<em><u>Substituting the values we get,</u></em>

Thus volume of sand box is 110.7 cubic feet
Mr. Berger plans to fill the sandbox half full of sand
So find half the volume
volume of sand he will need to fill half of the sandbox is given as:

Thus the volume of sand he will need to fill half of the sandbox is 55.35 cubic feet
