The distance from A to B is one-third of the distance form A to D
The distance from C to D is one-quanter of the distance from A to D.
The distance from B to C is 150 millimetres.
What is the distance from A to D?
................. millimetres
A B C D
Length AB = 1/3 of AD
Length CD = 1/4 of AD
Length BC = 150 mm
So, Length AD = Length AB + Length BC + Length CD
AD = 1/3 AD + 150 mm + 1/4 AD
AD = 7/12 AD + 150 mm
( AD - 7/12 AD) = 150 mm
5/12 AD = 150 mm
AD = 360 mm
ANSWER = Distance from A to D is 360 millimeter
- By Ethan
AB= 1/3AD
CD=1/4AD
BC=150mm
SOLUTION:
AB+BC+CD=AD
1/3AD+150+1/4AD=AD
7/12AD+150=AD
5/12AD = 150
AD=360
