Answer / sneha
let the time travelled aftr travelling 180m be t
so the eqn becomes
180+x*t=10*x*t
solving we get xt=20
and total distance travelled is 180+20=200m

Answer / praveen
let Xmph be the speed of the ship. so after 1 hour it would
have travelled 180+x miles . and the plane would have
travelled 10x miles..
so the distance covered by the train and the plane is
180+x=10x;
180=9x;
x=20
so the distance travelled by the train is 180+20=200miles.

Answer / neha
Let ship and plane meet after d miles after 180 miles from
starting point.
Let t be the time taken to travel d miles by ship & 180+d
miles by plane
So the eqn is:
Time taken by ship to travel d by ship = Time taken by
plane to travel 180+d miles
d/x=180+d/10x
on solving, we get d = 20 miles
So they meet after 180+20 = 200 miles from starting point.
Ans = 200 miles

Answer / muhammed fayis pm
assume velocity of ship v1=1m/sec.so velocity of plane
v2=10m/sec.hence to reach 180 mile,plane takes 18sec,at
this time ship has covered 198miles.plane takes 1 sec to
reach 190mile from 180.while ship is at 199mile.plane
againe took 1 sec to reach 200 from 190.during this
remaining 1sec of ship, reaches to 200mile.so they meet at
200th mile
