Yes, they both are, and you'd just be working with complex numbers instead of real number.
Speed is constant. 50 miles = 1 hour. 600/50 = 12. 1hr(12) = 12 hours.
Answer:
The liquid contained in batteries that conducts electric charge is called the. electrolyte.
Answer:
has units of distance
has units of distance over time
has units of distance over 
has units of distance over 
Explanation:
Since the expression for the distance is:

then:
has units of distance
has units of distance over time
has units of distance over 
has units of distance over 
because we are supposed to be able to add all of the terms and get a distance. So the products on each term that contains factors of time (t) should be cancelling those time units with units in the denominator of the multiplicative constant s that accompany them.
