You multiply using the distributive property.... Hope it helped :)
The conditional, <span>If four points are non-coplanar, then they are non-collinear, </span>is true:
This is, coplanarity is a necessary condition to be collinear.
The converse, <span>If four points are non-collinear, then they are non-coplanar, is false.
A counterexample that disproves this statement is the 4 vertices of a paralelogram, of course they are in a same plane and are not collinear.

First we need to find the rate which is the total amount driven divided by the total time.
152/4 = 38 miles per hour.
No we take the total driven miles given and divide it by the rate to find how long it would take!
760/38 = 20 hours!
Hope this helps :D
