Let b and p represent the distances traveled by baby and pickles, respectively.
.. b +p = 27
.. p = 5(3b -1)

Substituting, you have
.. b +5(3b -1) - 27
.. 16b -5 = 27
.. 16 b = 32
.. b = 2

The baby travel was 2 miles.
The pickles travel was 25 miles.

If an object is projected upward into the air from ground level, then the height h(t) of the object
AfilCa [17]

Answer:

21.5secs

Step-by-step explanation:

Given the function that models the height of an object as

h(t) = -16t^2+ 344t

The object hit the ground at h(t) = 0

Substitute

0 =  -16t^2+ 344t

16t^2 = 344t

16t = 344

t = 344/16

t =  21.5

Hence it takes 21.5secs for the object to hit the ground
