i think ans- 8 m/s
time for sonia to cover 1 round (125 m) dist = 125/4 sec
in same time Rahul cover 2 rounds; then rahul speed = 2*125/(125/4) = 8m/s

Distance covered by sonia in walking when rahul was riding on bicycle = 125-45 = 80 m
waking speed of sonia is given i.e 4m/sec
so, time taken by sonia to cover this 80 m is = 80/4=20 sec.
Now,in this 20 seconds Rahul completed 2 rounds
So,time taken by rahul to complete 1 round by bicycle = 20/2=10 sec
Distance covered by rahul through riding is 80 m because after this he walked remaining 45 m together with sonia
So, the speed while riding bicycle will be = Distance/time=80/10 = 8m/sec

After 2 rounds they walk together for 45 meters ... there is no use of it....
sonia will take 125/4 sec to cover 1 round 125 meter
In same time rahul cover 2 round means 250 meter
125/4=250/v
v=8 m/s

DAMARLA BALAJI  (9 years ago)

I think a) 8m/s bcz
rahul 2 rounds distance=125+125+125+125=500mts
from t=d/s
t=500/8(also written as 250/4) or 500/14 or 500/20 or 500/10
sonia 1st round=125+125mts
t=250/4 so option a is right
