select the correct statement.

it takes tony 20 minutes to reach the finish line.

tony reaches a maximum distance of 3,750 meters over the interval [6, 10].

tony's speed increases to 225 meters per minute.

For this case, what we are going to do is write the linear function that models the problem.
 We have then:
 y = -250x + 5000
 Where,
 y: distance traveled
 x: time in minutes
 To reach the goal (y = 0) we have:
 0 = -250x + 5000
 250x = 5000
 x = 5000/250
 x = 20 minutes
 
 It takes Tony 20 minutes to reach the finish line.
