Acar is moving on the distance 35km in the time 30minutes, stays 20 minutes, the it moves again vith the velocite 60km/h in 25 minutes: a)the first velocity on the first part of the road b)the distance driven on the last part of the road c)the average velocity in meters/seconds

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?
