问题 Two trains running on parallel tracks are 600 miles apart. One train is moving east at a speed of 90 mph, while the other is moving west at 75 mph. How long will it take for the two trains to pass each other?
选项
答案  This is a standard Rate×Time=Distance problem. Since the two trains start 600 miles apart, the combined distance traveled by both trains must equal 600. Using the R×T=D formula, you know that (Rate of Train 1×Time of Train 1)+(Rate of Train 2×Time of Train 2)=600. You are given that the rate of travel is 90 mph for the first train and 75 mph for the second train, and the distance traveled is 600 miles; therefore, you must solve for T, as follows:
   90T+75T=600
      165T=600
         T=(approximately) 3.64 hours
