Two trains

There are two trains running the same distance. 1st train will travel it in 7 hours 21minutes. 2nd the train will travel 5 hours 57minutes and 34 seconds and it is 14 km/h faster than the first train. What are speeds of trains and how long is this railway?

Correct answer:

a =  60 km/h
b =  74 km/h
s =  441 km

Step-by-step explanation:


a-b = -14
26460a-21454b = 0

a = 59.999201
b = 73.999201

Our linear equations calculator calculates it.
b=73.9992=74 km/h
s=a (7+21/60)=59.9992 (7+21/60)=441 km
