Question

ritika walks 25 km in 5 hr and dinesh walk 21 km in 7 hr find the ratio of their speeds

Answer 1

Speed of ritika :

Distance / time = 25 / 5 = 5 km/h.

Speed of dinesh :

Distance / time = 21 / 7 = 3 km/h.

Now, ratio of their speed :

$= > \frac{speed \: of \: ritika}{speed \: of \: dinesh} \\ \\ = > \frac{5}{3} \\ \\ \therefore { \boxed{ \bold{5 : 3}}}$
