There is a fly and there is a car. Car runs at 10m/sec and fly flies at 20m/sec.
The fly starts flying from a point X towards the coming car, touches it, and then fly back to X again. It again flies back to car..touches it and den fly back to X. This whole continues till the car reaches X.
The initial distance between car and X is 1km.
How much distance the fly travelled in the direction of car?
hi
using the sme concept as i explained in your previous thread
this time fly will move .93 Kmetres (overall) in direction of car.
.93 is combination of three parts! (i.e .66+.22+.05)
bye
:D
The answer - for obvious reasons- is 1km. The distance travelled by fly will turn out to be geometric series with a=666.67 and r=1/3. This will be an infinite series converging towards zero.
Hence, sum = a/(1-r) = 666.67/ (1-.3333) = 1km.

y only 3 terms??
hi kalayama
now wt will be the total distance travelled by fly?
Once again, for obvious reasons it should be 2kms (1km + 1km).
