Which is a stretch of an exponential decay function?
f(x) =4/5(5/4)^x

f(x) =4/5(4/5 )^x

f(x) =5/4(4/5)^x

f(x) =5/4(5/4)^x

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
