Hence, the required distance = 5 96/60 km = 8 km. We can use the distance = rate time formula to find the distance Lee traveled. If his total time of travel back and forth is 3 hours and 10 minutes, the distance from the barrio to the poblacion is : A. If the distance moved by a car, before the person applies brakes is 5m, the reaction time of the person is: A 0.5 s B 0.10 s C 10 s D 0.25 s Medium Solution Verified by Toppr Correct option is D) v=72km/hr= 18725=20m/s Time taken to cover the distance of 5m is: r be the rate of speed the car is traveling t be the time the car has been traveling.
