avg velocity is 40 mi/hr = 17.88 m/s
so the distance should be at least 17.88 * 10.8 = ____ m
Anette is a civil engineer and needs to determine the length of a highway on-ramp before construc-
tion begins. If the average vehicle takes 10.8 s to go from 20.0 mi/h to 60.0 mi/h, how long should
she design the separate merge lane to be so a car can reach a speed of 60.0 mi/h before merging?
