The 5.25 m combined height of John, Jim, and Joe, the 12 cm height difference between John and Jim and the 0.09 m difference in height between Jim and Joe, indicates that solution to the word problem is Joe was 1.73 meters tall
<h3>What is a word problem?</h3>
A word problem is a presentation of a math problem using verbal description rather than numbers, variables and operators.
The combined height of John, Jim and Joe = 5.25 m
John's height = Jim's height - 12 cm = Jim's height - 0.12
Jim's height = Joe's height + 0.09 m
Let <em>h </em>represent Joe's height, we get;
Jim's height = h + 0.09
John's height = h + 0.09 - 0.12 = h - 0.03
John's height = h - 0.03
The sum of the heights is therefore; h + h + 0.09 + h - 0.03 = 3·h + 0.06
The sum of their heights = Their combined height = 5.25 meters
Therefore; 3·h + 0.06 = 5.25
h = (5.25 - 0.06)/3 = 1.73
Joe's height, <em>h</em> = 1.73 meters
Jim's height = 1.73 + 0.09 = 1.82
Jim's height = 1.82 meters
John's height = 1.73 - 0.03 = 1.7
John's height is 1.7 meters
Joe was 1,73 meters tall
