relative speed =5/2 - 2,
=(5-4)/2,
=1/2 =0.5 km/hr,
then
time taken=distance/speed,
time taken =18/0.5,
=180/5,
=36 hr
=(5-4)/2,
=1/2 =0.5 km/hr,
then
time taken=distance/speed,
time taken =18/0.5,
=180/5,
=36 hr

THE SPEED OF SARITA=2km/h
Sarika determines the distance 5/2km in 1hr..

Sarita determines the distance 2km in 1hr
