Answer 2

Answer:

Lolly run 30km in 75 min and Divya run 12 km in 40min . Who between them runs faster ?

Solution:

Lolly runs 30 km in 75 minutes

Distance (Lolly) = 30 km

Time (Lolly)= 75 min

75 /60 hours = 1.25 hours

So,

Speed of lolly =

= 30/1.25 kmph

Divya runs 12 km in 40 min

Distance (Divya) = 12 km

Time (Divya) = 40 min

= 40/60 = 2/3 hours

Speed of Divya =

12 /⅓ = 12*3/2 = 18 kmph

So ,

Clearly Lolly run faster
