Question

in a 100m race kamal defeats bimal by 5 seconds. if the speed of kamal is 18 kmph then the speed of bimal is

Answer 1

speed=distance/time
=100/5
=20kmph
so speed of bimal is 20kmph

Answer 2

Hii..
Here is your answer..

Solution:-
Distance travelled by Kamal =100m
Speed of Kamal =18km/h
To convert it into m/s we'll multiple it by 5/18
$= > 18 \times \frac{5}{18} \\ = > 5m \: per \: sec$
Since,
$time = \frac{distance}{speed} \\ = > \frac{100}{5} \\ = > 20sec$
Now,
Time taken by Bimal =20+5
=>25sec
Distance travelled=100m
Speed=Distance/Time
$= > \frac{100}{25} \\ = > 4m \: per \: sec$
To convert it into km/h we'll multiple it by 18/5
$= > 4 \times \frac{18}{5} \\ = > \frac{72}{5} \\ = > 14.4km \: per \: hrs$
Hence,Speed of Bimal=14.4km/h

Hope it helps uh...✌️✌️✌️
