Please explain

A trafficsafety engineer is designing a deceleration lane. She is basing the length of this lane on the distance needed to slow down from 126 km/h to 65 km/h in 8.05. How long will the deceleration lane be? Select one: a. 2.1 x 102m b. 3.8 x 102m " c. 4.2 x 102 m d. 7.6 x 102 m Check The graph below shows the acceleration over a 10 s interval of a car merging into highway traffic from an accelration lane. How far did the car travel during this time interval? Velocity-Time Velocity (m/S) 7 +, I. L f l Select one: Q a. 100 m
