Answer:
4.33 miles
Step-by-step explanation:
20 minutes=1/3 of an hour
because 1 hour=60minutes
so 20/60 = 1/3
for your answer
13× 1/3=4.33
therefore she was able to bike 4.33 miles in 20 minutes at a constant speed
The discriminant is the term under the radical sign in the quadratic formula.
x=(-b+-(b^2-4ac)^(1/2))/(2a)
It is the b^2-4ac part. (a,b,c from the standard quadratic of form ax^2+bx+c)
In this case:
10^2-4*3*4
100-48
52
