Question 1121101: On a 100 cm ruler, lines are drawn at 10, X, and 98 cm. The distance between the lines at X and 98 cm is three times the distance between the lines at X and 10 cm. What is the value of X?

Let d = the distance between the lines at X and 10 cm.
Then 3d = the distance between the lines at X and 98 cm.
The total distance is 100 cm so we can write the following:
10 + d + 3d + 2 = 100
4d = 88
d = 22
The distance between 10 and X is 22, therefore X = 32
