Answer:

$24(f(n))$

Step-by-step explanation:

$f(n+3) = 3^{n+3}\\f(n+1) = 3^{n+1}$

$f(n+3) - f(n+1) = 3^{n+3} - 3^{n+1}$

$= 27(3^n) - 3(3^n)$

$= 24(3^n)$

$= 24(f(n))$

The average speed of one team in a relay race is about 10 miles per hour. What is the speed in feet per second?

ki77a [65]

10 miles per second in feet per second is 14.67 feet per second

Step-by-step explanation:

The average speed of one team in a relay race = 10 miles per hour.

We need to find the speed in feet per second.

The conversion rule is:

1 mile per hour = 1.467 feet per second

So, Speed in feet per second is:

1 mile per hour = 1.467 feet per second

10 miles per hour = 10*1.467 feet per second

= 14.67 feet per second

So, 10 miles per second in feet per second is 14.67 feet per second
