After traveling for 4 hours and 18000 miles ,an airplane begins a steady descent when it begins descending its altitude(height) is 33,000 feet . After 8 mins it is at 17,000 feet write a function that models the planes altitude

its 4 because 2 times 2 is 4, if you double the number two you get four

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.
