Question

To determine the order that cars line up for the Daytona 500, drivers must complete qualifying laps around the Daytona International Speedway. The fastest ever qualifying lap was in 1987 by Bill Elliott, with a time of 42.782 seconds.That was 210.364 miles per hour (or 338.548 kilometers per hour).

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

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

Answer 1

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

Explanation:

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

`Frequency = (1)/(Time)`

`Frequency = (1)/(42.782)`

`Frequency = 0.0233743`

No. of laps completed in 42.782 seconds. = 1

No. of laps completed in 60 seconds. =
`(1)/(42.782) * 60`

=
`1.4024`

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