Answer 2

Heya mate,Here is ur answer

1 m = 1/1000 km

100 m =100/1000 km

100m = 1/10 km

1 min =1/60 hr

2 min =2/60 hr

2 min =1/30 hr

so, the question becomes Ravi t
can swim 1/10 km in 1/30 hr. Find his speed.

Speed = distance/time

$= \frac{ \frac{1}{10} }{ \frac{1}{30} }$


$= \frac{30}{10}$


$= 3 \: km \: per \: hr$


So, the speed of Ravi is 3 km/hr.
