Suppose a car going 65 mph is traveling north parallel to a train going 50 mph. Once the front of the car is as far north as the back of the train it takes another three minutes for the front of the car to be further north than the front of the train. How long is the train?

0.75 Miles

Step-by-step explanation:

To find the answer we have to find the difference in the distance the train and car travelled

65/60 is 1.083333 which is miles per minute then multiplied by 3 is 3.25 mile gone in 3 minutes

For the train it is 50/60 which is 0.833333 and the times 3 is 2.5 miles in three minutes

3.25 miles minus 2.5 miles is 0.75 miles so that is how long the train is

ok then what happened.
