Question 353635: One train runs 90% of the time and goes 55 mph any time it runs (no acceleration lag time) Another train runs 10% of the time. How fast does this train have to go (mph) to exceed the distance of the other train? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 1st train:
9*55=495 mi in 10 hrs
2nd train would have to travel at greater than 495 mph to exceed the distance of the other train.
