Using a graphing calculator, we can see the graph of the function y = x²-4x+1:
as we can see, the vertex of the function is (2,-3), and the solutions are (0.3,0) and (3.7,0)
The minutes it takes him to run 10.5 miles is 180 minutes
<h3>How many minutes did it take him to run 10.5 miles?</h3>
The given parameters are
Speed = 3.5 miles per hour
Distance = 10.5 miles
The time is calculated as:
Time = Distance/Speed
So, we have
Time = 10.5 miles/3.5 miles per hour
Evaluate the quotient
Time = 3 hours
Convert to minutes
Time = 180 minutes
Hence, the minutes it takes him to run 10.5 miles is 180 minutes
