Average velocity and displacement - by <your name>, <year>

1. Heather and Matthew walk eastward with a speed of 0.98 m/s.  If it takes them 34 min to walk to the store, how far have they walked? 

Here's what you know, Dt = (34 min)(60 sec/min) = 2040 sec, and v_avg = 0.98 m/s.  Use the formula  v_avg = Dx/Dt and plug in: 0.98 m/s = Dx/2040 sec, so Dx = (0.98m/s)(2040 s) = 1999.2 m = 2.0 km (1000 m = 1 km)
