Let X be the speed of the slower train in km/hr
speed of other one will be (x+5) km/hr.
Now,
distance travelled by slower train in 2 hrs= speed × time
= x×2
= 2x
distance travelled by Faster train in 2 hrs= 2*(x+5).
Now ,
2x+ 2(x+5) +50=200
→x= 35km/hr see picture
speed of second train = 30+5 = 35km/hr
speed of other one will be (x+5) km/hr.
Now,
distance travelled by slower train in 2 hrs= speed × time
= x×2
= 2x
distance travelled by Faster train in 2 hrs= 2*(x+5).
Now ,
2x+ 2(x+5) +50=200
→x= 35km/hr see picture
speed of second train = 30+5 = 35km/hr
