Answer:

Ayush's route is 700 meters or 0.7 km longer than Sumit's route.

Step-by-step explanation:

We have been given that Ayush and Sumit take two different routes to school. Ayush's route is 1 km 2 hm long while Sumit's route is 2 hm 30 dam long.

First of all, we will convert each of our given distances into meters.

1\text{ km}=1,000\text{ m}

\text{ 1 hm}=100\text{ m}

\text{ 2 hm}=2\cdot 100\text{ m}=200\text{ m}

\text{Distance covered by Ayush}=1,000\text{ m}+200\text{ m}=1200\text{ m}

\text{1 dm}=10\text{ m}

\text{30 dm}=30\cdot 10\text{ m}+300\text{ m}

\text{Distance covered by Ayush}=300\text{ m}+200\text{ m}=500\text{ m}

Since 500 meters is less than 1200 meters, therefore, Ayush's route is longer.

Let us find the difference between both routes as:

\text{1200 m}-500\text{ m}=700\text{ m}

Therefore, Ayush's route is 700 meters longer that is equal to \frac{700}{1000}\text{ km}=0.7\text{ km}.

Answer:

Ayush's route is 0.7 km or 700m longer than Sumit route.

Step-by-step explanation:

Ayush's route is 1km 2hm long while sumit route is 2hm 30dam.

We know that,

1 km = 10 hm

1 dam = 0.1 hm

Using these conversions we get

Ayush's route = 1km 2hm = (1×10) hm + 2 hm = 12 hm

Sumit route = 2hm 30dam = 2 hm + (30×0.1) hm = 2 hm + 3 hm = 5 hm

Ayush's route is longer.

Difference = 12 hm - 5 hm = 7 hm = 0.7 km            [1 km = 10 hm]

Hence, Ayush's route is 0.7 km or 700 m longer than Sumit route.
