speed of Kanta=150m/min=9000m/60min
speed of Suman=8km/hr=8000m/60min
total distance=3km800m=3800m
time taken by Kanta to cover the distance=25.3bar=25.4 minutes
time taken by Suman =28.5minutes
so Kanta will win the race with less time
speed of Suman=8km/hr=8000m/60min
total distance=3km800m=3800m
time taken by Kanta to cover the distance=25.3bar=25.4 minutes
time taken by Suman =28.5minutes
so Kanta will win the race with less time

Distance = 3800 m
speed of kanta =150m/min
speed of suman= 8km/hr
First we find speed of kanta
= 3800m×60 sec
= 4800 m/min
Speed = distance
speed
= 150
time
= 3800
Time
time = distance
time
time= 3800
150
time= 25.33 min answer ofkanta
suman = speed =distance/speed
8km =8000m/60 sec. =133.33
133.33= 3800/time
time = 3800/133.33 = 28.50 min answer of suman. kanta takes
[ kanta=25.33min ] less time so [Suman=28.50 min] she won
