A river has a steady speed of 0.474 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. (a) If the student can swim at a speed of 1.18 m/s in still water, how long does the trip take? (b) How much time is required in still water for the same length swim? (c) Intuitively, why does the swim take longer when there is a current?

A salesman drives from Ajax to Barrington, a distance of 120 mi, at a steady speed. He then increases his speed by 18 mi/h to drive the 169 mi from Barrington to Collins. If the second leg of his trip took 10 min more time than the first leg, how fast was he driving between Ajax and Barrington? I've been stuck on this for hours. I keep getting a decimal under the radicand and it's driving me crazy please help.

An object object travels 31 meters in the +x direction for 3.2 seconds, and then immediately travels some distance in the -x direction. After a total time of 7.7 seconds, the object's average velocity is 0 m/s. What is the average velocity for the second part of the trip (traveling in the -x direction) in m/s? If in the negative x direction, indicate so with a negative sign. PLEASE SHOW WORK!!!!
