A train travels a certain distance taking 7 hrs in forward journey, during the return journey increased speed 12km/hr takes the times 5 hrs.What is the distance traveled	Choose the correct choice from the following options:
A) 210 kms
B) 30 kms
C) 60 kms
D) 90 kms
E) 80 kms
let the speed in the forward journey be x km/hr, also   given time taken in fwd journey = 7 hrs   during return journey   speed=(x+12)km/hr   time=5hrs   nw distance travelled in both the cases is same therefore   forward journey distance=return journey distance   7x=5(x+12)   7x-5x=60   2x=60   x=30km/hr   therefore distance travelled= 30*7=

<output>210</output>
210km   or=5*(30+12)= 
<gadget id="calculator">5*(30+12)</gadget>
<output>210</output>
210km   210 kmsNSWER:210 kms
