if a man travels at a speed of 30 km/h he reaches his destination 10 m

1.	if a man travels at a speed of 30 km/h he reaches his destination 10 minutes late and if he travels at a speed of 42 km/h he reaches his destination 10 Minutes early the distance travelled is
Answer» Let the distance be x km. Then, correct time at a SPEED of 30 km / h =x/30-10/60 Correct time at a speed of 42 km /h =>x/42+10/60 =>x/30-10/60=x/42+10/60 =>x/30-x/42=2/6 =>x(12)/1260=2/6 =>72x=1260×2 =>x=1260×2/72 Therefore,x=35 km.

Answer»

Let the distance be x km.

Then, correct time at a SPEED of

30 km / h =x/30-10/60

Correct time at a speed of 42 km /h

=>x/42+10/60

=>x/30-10/60=x/42+10/60

=>x/30-x/42=2/6

=>x(12)/1260=2/6

=>72x=1260×2

=>x=1260×2/72

Therefore,x=35 km.
