Answer:

northbound: 2.5 hours
southbound: 1.5 hours

Step-by-step explanation:

When the second train leaves the station, the trains are already 63 miles apart. The rate of increase of their separation is (57 +63) = 120 miles per hour. The remaining 243-63 = 180 miles of separation will be achieved in ...

(180 mi)/(120 mi/h) = 1.5 h

The northbound train will have traveled 2.5 hours; the southbound train will have traveled 1.5 hours when the trains are 243 miles apart.

A small cube with side length 6y is placed inside a larger cube with side length 4x^2. What is the difference in the volume of t

olasank [31]

Answer:

64x⁶ - 216y³

Step-by-step explanation:

The formula for the volume of a cube is

Vol. = l³

For the large cube,

V =(4x²)³

V = 64x⁶

For the small cube,

v =(6y)³

v = 216y³

The difference in volume is

Diff. = 64x⁶ - 216y³
