Question

l ,m and n are the three cities on a straight line the distance between l andm is 260 kilometres, the distance between m and n is 180 kilometre and distance between l and n is 80 kilometre , which of them is between the two other​

Answer 1

Step-by-step explanation:

Given:

Distance between l and m = 260 km.. (1)

Distance between m and n = 180 km..(2)

Distance between l and n = 80 km......(3)

Adding (2) & (3)

Distance between m and n + Distance between l and n = 180 + 80 = 260

Therefore,

Distance between m and n + Distance between l and n = Distance between l and m

Hence l and m are extreme cities and n lies between both of them

So, l - n - m.
