A. What was the frequency of the car (measured in laps per second?)

B. How many laps were completed in 60 seconds (1 minute)?

Respuesta :

Answer:

The frequency of the car is 0.0233743 laps/sec and 1.4024 laps were completed in 60 seconds

Step-by-step explanation:

We are given that he fastest ever qualifying lap was in 1987 by Bill Elliott, with a time of 42.782 seconds.

[tex]Frequency = \frac{1}{Time}[/tex]

[tex]Frequency = \frac{1}{42.782}[/tex]

[tex]Frequency = 0.0233743[/tex]

No. of laps completed in 42.782 seconds. = 1

No. of laps completed in 60 seconds. = [tex]\frac{1}{42.782} \times 60[/tex]

                                                                = [tex]1.4024[/tex]

Hence the frequency of the car is 0.0233743 laps/sec and 1.4024 laps were completed in 60 seconds
