A train travels a certain distance taking 7 hrs in forward journey, during the return journey incr..

Answer / berend

420 km.
If v = speed on forward journey.
distance of forward journey = 7v
distance of return journey = 5(v+12) = 5v + 60
forward and return journey are equal so:
7v = 5v + 60
This means 2v = 60 and v = 30 km/hr.

The forward journey is 7*30 = 210 km.
The return journey is 5*42 = 210 km (not surprising).
Total distance traveled is 420 km.

Answer / haushila

x=speed
y=distance
according to the first situation ,
x=y/7...(1)
according to second situation,
x+12=y/5
or
5(x+12)=y
5x+60=y.....(2)
by subtracting equation 1&2
x=30

Answer / dinesh

suppose speed=x
distance travel=speed*timetaken

speed=x+12
timetaken=5

distance=5(x+12)

now solving this
7x=5(x+12)
x=30

so distance is 7*30=210
ans is 210;
