Question

A man walk 120 meter in a minute. how long will be take 21.6 km ?​

Answer 1

Answer:

240

Step-by-step explanation:

Given  

A man walks 110 m in a minute.How long will he takes to walk 26.4 km

Now we need to convert km to m.

We know that 1 km = 1000 m

So               26.4 km = 26.4 x 1000 m

                                    = 26,400 m

A man walks 110 m in one minute.

So he walks 26,400 m in 26,400 / 110 = 240 min

So he takes 240 min or 4 hrs to walk.

Answer 2

Answer:

distance walked = 120m or 0.12 km

time taken = 1 min

therefore, 0.12km or 12/100 = 1min

1km = 1/12/100

= 100/12min

21.6 or 216/10 km = 100/12 × 216/10

= 10 × 18

= 180min or 3 hours
