A highway engineer wants to estimate the maximum number of cars that can safely travel on a particular road at a given speed. She assumes that each car is 15 feet long, travels at speed s, and follows the car in front of it at a safe distance for that speed. She finds that the number N of cars that can pass a given spot per minute is modeled by the function N(s)
N (s) = (81s) /(17+17(s/20)^2)
At what speed can the greatest number of cars travel safely on thatroad?

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

30005

yes ok
