A fast train takes 3 hours less than a slow train for a journey of 600 km. If the speed of the slow train was 10 km/h less than that of the fast train , find the speeds of the trains .
let the speed of slow train = x km/hr.
and the speed of fast train =( x+10) km/hr
Time to cover 600 km by slow train = 600/x hrs.
Time taken by fast train to cover 600 km = 600/(x+10) hrs
∴According to question,
∴The speed of slow train = x km/hr = 40 km/hr
and the speed of fast train =( x+10) km/hr= 40+10= 50 km/ hr
