Question

Prateek travel 600 km to his home partly by train and partly by car he takes 8 hours if he travels 120 km by train and the rest by car he takes 20 minutes longer, if he travels 200 km by train and the rest by car find the speed of the train and the car

Answer 1

HEY DEAR ... ✌

___________________________




Let the speed of the train be x km/hr and speed of car be y km/hr
Prateek travels 120 km by train, the distance covered by car 600-120 = 480 km
Now, time taken to cover 120 km by train = 120/xhr
And time taken to cover 480 km by car = 480/y 
Total time taken to travel 600 km = 120/x + 480/y = 8 hr (i)
Similarly 
200/x + 400/y = 8hr. 20minute = 8(20/60) (ii)

solve (i) and (ii) 
we get 
x = 60 km/hr and y = 80 km/hr

HOPE , IT HELPS ... ✌
