Answer:
  t = 1.58 s
Explanation:
given,
Speed of ranger, v = 56 km/h
                             v = 56 x 0.278 = 15.57 m/s
distance, d = 65 m
deceleration,a = 3 m/s²
reaction time = ?
using stopping distance formula


t is the reaction time

  t = 1.58 s
hence, the reaction time of the ranger is equal to 1.58 s.
