Answer
32 ms
Work Step by Step
Let's say the distance between the hand and brain is .8 m
We need to find time so using speed= distance/time we can solve for time.
time = distance/speed
speed = 25 m/s
distance = .8 m
t = .8 m/(25 m/s)
t= 0.032 s
Then convert to ms by multiplying by 1000 to get 32 ms
