Answer:
10 hours.
Step-by-step explanation:
Two bicyclists are 200 miles apart when they start racing towards one another.
Their speeds are 12 mph and 6 mph respectively.
Distance = speed × time
Let the time taken by bicyclists = t
We have to calculate the time when they 20 miles apart this means they have covered the distance of 200 - 20 = 180 miles
t(12mph) + t(6mph) = 180
18t = 180
t = 
t = 10 hours
It will take 10 hours to both the bicyclists before they are 20 miles apart.
Answer:
Brand C
Step-by-step explanation:
Answer:
The value of Discriminant of the function is -92
It has ZERO distinct real number zeros.
Step-by-step explanation:
Given:
Which is a Quadratic Equation in the general form of
where a,b and c are constants.So on comparing the given equation with general form we get,
Formula for discriminant we have
now for zeros we have
on substituting these values we get
or
the term 
is imaginary
hence the zeros are not real number
