Answer: Seth is travelling at 63.047mi/hr
Step-by-step explanation: First convert 57.1 seconds to hours.
1 hour is equal to 3600s so multiply 57.1sec by 1hr/3600s to get 0.0158 hr
The formula for speed distance over time. v=d/t
v= 1mi/0.0158hr
v= 63.047mi/hr
Answer:
This equation has no real roots
Step-by-step explanation:
We want to solve

We group all terms on the left:


Divide through by -6

The discriminant is

This means the given equation has no real solution, since the discriminant is less than 0
