Question

A trains runs at a speed of 75 km per hour. how far does it cover in 5 hours 30 minutes. the book's answer is 825/2​

Answer 1

Answer:

ANSWER

Let  the correct time for the train to complete the journey is x minuets

Then train cover distance in x+11 minuets at speed 40 km\hr =6040(x+11)km

Then train cover distance in x+5 minuets at speed 50 km\hr =6050(x+5)km

Both are same then 6040(x+11)=6050(x+5)

∴40x+440=50x+250

∴−10x=−190

∴x=19 minutes
