ans: 9000km

Answer 1

Answer:

moment,a jet plane whose speed is 10 times the speed of ship took off from the port. After travelling how much distance will the plane overtake the ship ?

let d=distance ship traveled after plane took off

8100+d=distance plane traveled to overtake ship

x=speed of ship

10x=speed of plane

travel time=distance/speed (same for both ship and plane)

d%2Fx=%288100%2Bd%29%2F%2810x%29

10x%2Fx=%288100%2Bd%29%2Fd

10=%288100%2Bd%29%2Fd

10d=8100+d

9d=8100

d=900

1800+d=9000

distance plane traveled to overtake ship=9000km
