Question

. Maheep travels 600 km partly by train and
partly by car. He takes 8 hours to cover the
whole distance if he travels 120 km by train
and rest by car. But he takes 20 minutes
longer if he travels 200 km by train and the
rest by car. Find the speed of train and car.​

Answer 1

Answer:

speed train=60km/he speed car=80km/hr

Step-by-step explanation:

let speed of train-a speed of car-b

case 1

total time taken = 8 hrs

time by train- 120/a

time by car- 480/b

so 120/a + 480/b = 8.......eq 1

case 2

total time taken= 8 + 20/60

= 25/3 hrs

time by train- 200/a

time by car =400/b

so 200/a +400/b = 25/3.........eq 2

solve eq 1 and eq 2.
