You must travel at 42 mph for 4 hours
<em><u>Solution:</u></em>
Time varies inversely as rate of motion
Let "t" be the time required
Let "r" be the rate of motion
Then, we get

Where, "k" is the constant of proportionality
<em><u>You travel 3 hours at a rate of 56 mph</u></em>
Substitute t = 3 and r = 56 in eqn 1

<em><u>Find the rate you must travel for 4 hours</u></em>
r = ? and t = 4
Substitute t = 4 and k = 168 in eqn 1

Thus you must travel at 42 mph for 4 hours
Im not sure what you are trying to ask but any investment can be risky, yes.
I don't think its possible to do this... you have to have 2 equations
ANSWER
36 cubic inches.
EXPLANATION
The volume of a square pyramid is calculated using the formula:

where l² is the area of the base and h= 6 inches is the height of the square pyramid.
We substitute the values into the formula to get,

We simplify to get:

Therefore the volume of the square pyramid is 36 cubic inches.
