Answer:
1.14 s
Step-by-step explanation:
Time, 
Here, d is the distance and s is the speed/velocity
Since we're given the velocity, s as 28 ft/s and the distance between the position of the rocket and ground as 32 ft then

Therefore, it needs 1.14 seconds
Simple,
1/2 of 60
re-write it as 0.5 of 60 aka 0.5*60
which is 0.5*60=30
Do the same with 1/2 of 24.
0.5 of 24
0.5*24=12.
Thus, it's not the same because they are different numbers and different number give you different answers.
3/5 × 20/1 = 12 because 3×20 is 60 and 5×1 is 5 so 60/5 and that simplifies to 12
I think its 6 but im not sure to be exactly right
