Your answer is B.
If you need anymore help feel free to ask me!
Hope this helps.
Answer:
14.0 m
25.1 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Distance traveled in the reaction time
Distance = Speed × Time


Distance in which the car will stop is 10+20 = 30.0 m
So, the car will not hit the deer
Distance between the car and deer is 44-30 = 14.0 m



Maximum speed of the car by which it will not hit the deer is 25.1 m/s
Maybe when you ice-skate 10 times per second around a 1-foot circle.
