viru 's speed=15km/hr
mumaf speed=5m/s=18km/ hr
since 18>15
munaf win the race.
now, distance=400m
munaf speed=5m/s
time taken by munaf to cover the distance of 400m=d/s=400/5s=80second.

anishram: yes exactly correct
Mausam11: thnx

firstly we need to convert Munaf's speed to km/hr

5 × 18/5 = 18km/hr
As Munaf's speed is more,

1) Munaf will win the race.

2) time = distance/speed
t = 400/5

time taken = 80 seconds to complete 400 m

mark brainliest if it helps, Thanks
