Study the bar graph and answer the following questions:

Scale: 1 unit length = 200 km

1. Which National Highway (N.H.) is the longest among the above?
2. Which National Highway is the shortest among the above?
3. What is the length of National Highway 9?
4. Length of which National Highway is about three times the National Highway 10?

Answer 1

1. The longest National Highway is N.H. 2.
2. The shortest National Highway is N.H. 10.
3. The length of National Highway 9 is 900 km.
4. Length of National Highway 10 = 450 km
   Length of National Highway 8 = 1400 km
   So, length of National Highway 8 is about three times the National Highway 10.
