Question

In an 800 meters race, ammu beats minnu by 80 meters and chinnu by 200 meters. If ammu takes 40 seconds to finish the race, what is the ratio of the times taken by ammu.Minnu and chinnu to finish the race

Answer 1

Answer:

Minnu takes 400/9 seconds.

Chinnu takes 160/3 seconds.

Step-by-step explanation:

Ammu finish race in 40 seconds.

In 40 seconds Minnu completed only (800 - 80) meters

So Minnu covered 720 meters in 40 sec.

for 800 meters, Minnu takes

800*40/720=400/9 seconds.

Chinnu is able to finish only (800 - 200) meters in 40 seconds.

so in 40 seconds Chinnu covers 600 meters.

for 800 meters, Chinnu takes

800*40/600 = 160/3 seconds.
