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
3.64 hours
解析
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 x 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
