solving inequalities??? HELP me please =/?

Question

19. The velocity of an object fired directly upwars is given by V=35-9.8t, where (t) is time in seconds. Which inequality describes the velocity when (t) is between 0.5 and 1.5 seconds? {HINT: remember that when you multiply an inequality by a negative number, you must switch the direction of the inequality.}

MY WORK: solving inequalities

0.5 < 35-9.8t < 1.5
0.5-35 < 35-35-9.8t < 1.5-35
-34.5 < -9.8t < -33.5
-34/-9.8 > -9.8/-9.8 > -33.5/-9.8
3.52 > t > 3.41
[This is what I got, but is not in the answer choices. What am I doing wrong can someone please help me?]

Below are the answer choices:

A.)20.3 > 35-9.8t > 30.1
B.) 4.9 > t > 14.7
C.) 0.5 < t < 1.5
D.) v < 30.1
E.) 20.3 < 35-9.8t < 30.1
F.) 14.7 > 35-9.8 > 4.9

Answer 1

the question is
Which inequality describes the velocity when (t) is between 0.5 and 1.5 seconds

t is between 0.5 and 1.5 seconds
not v

0.5 < t < 1.5
-9.8*0.5 > -9.8t > -9.8*1.5
-4.9 > -9.8t > -14.7
35-4.9 > 35-9.8t > 35-14.7
30.1 > 35-9.8t > 20.3
or
20.3 < 35-9.8t < 30.1

Answer 2

Actually, your work shows that you are solving for t. However, you are given t, and should be plugging in those values instead.

You would plug in 0.5 and get 35-9.8(0.5) = 30.1.

Then you would plug in 1.5 and get 35-9.8(1.5) = 20.3

Keep in mind the problem asks for velocity which is 35-9.8t. Therefore, the answer is E.) 20.3<35-9.8t<30.1

hope this helps.

Answer 3

you found t
you need to find v

for t=0.5
v=35-9.8*0.5=30.1

for t=1.5
v=35-9.8*1.5=20.3

v2
20.3<35-9.8t <30.1

The answer is
E.) 20.3 < 35-9.8t < 30.1

Answer 4

C) 0.5 < t < 1.5
E) 20.3 < 35-9.8t < 30.1
