Answer:
A) Juan wins the race
B) J(t) = A (t) at (7 minutes, 2 miles)
C) The interval is 7 minutes to 15 minutes
Explanation:
a) Juan wins the race
The reason is that the time Juan took to cover the distance of 4 miles is shorter than the time Antonio took
b) J(t) = A(t) at what point
This simply refers to the point at which the two graphs cross over one another
We can see this at the point ; (7,2)
This is; 7 seconds and 2 miles
What this mean is that they both covered 2 miles in 7 seconds
c) interval where J(t) > A(t)
This is the interval at which Juan was ahead of Antonio
Juan was below within 7 minutes
after 7 minutes he picked up
so the interval is 7 minutes - 15 minutes
