Answer:
City B is in between City A and City C
Given : A, B, & C are three cities on the straight road such that distance between city A and city B is 75 km & distance between city A & city C is 125 km
To Find : Is distance between city c and city B is 50 km
which city is between the other two Justify
Solution:
Distance between A and B = 75 km
Distance between A and C = 125 km
if A is in between B and C
Then Distance between B and C = 75 + 125 = 200 km
B --75 km --- A ---- 125 km ---- C
if B is between A and C
Then AC = AB + BC
=> 125 = 75 + BC
=> BC = 50 km
A -- 75 km -- B --- 50 km -- C
if C is between A and B
then AB = AC + BC but AC > BC
Hence not possible
So If distance between city C and city B is 50 km then City B is between A and C
If A is in between B and C then distance between city C and city B is 200 km
