Distance, Rate, and Time Problems
Date: Wed, 22 Mar 1995 14:17:25 AST From: Richard Seguin Subject: Rate, Distance, Time... I have a question like this: 1) Liza and Tamar leave the same camp and run in opposite directions. Liza runs 2m/s and Tamar runs 3m/s. How far apart are they after 1 hour? What I did was: Liza ---- Have to convert from Sec to hours. 3600 = sec in hours (2m/s)(3600)=7200 M/H Now I converted it to KM: 7200M = 7.2KM So she would be 7.2KM Tamar: ------ (3M/S)(3600)=10800M/H Converted to KM 10800 = 10.8 KM They all together would be 18KM apart. Right?

Jon travels at 12km/h, while Jennifer travels at 16km/h. After 6h, how far apart are they? What I did was: Jon --- D=Vt D=(12)(6) D=72KM Jennifer -------- D=VT D=(16)(6) D= 96KM 96-72 = 24 Km apart Is this right? I think I am getting the hang of this.
