正确答案:×
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
