plz give an appropriate answer.​

Answer 1

Answer:

speed of car = 80km/hr

speed of train = 60km/hr

Step-by-step explanation:

let speed of car be y km/hr

let speed of train be x km/hr

ATQ

60/x +240/y = 4 ---------- equation 1

100/x +200/y = 4+10/60 -------------equation 2

let 1/x be a

1/y be b

so 60a +240b = 4

100a +200b=25/6

by solving these equations we get a= 1/60 and b = 1/80

=> x = 60 km/hr

y = 80 km/hr
