Question

The points Q, R, S and T all lie on the same line segment, in that order, such that the ratio of Q R : R S : S T QR:RS:ST is equal to 6 : 3 : 1. 6:3:1. If Q T = 10 , QT=10, find R S . RS.

Answer 1

RS = 3?

I will draw a diagram because its easier that way. If QS = 9 since 6 + 3 = 9 and QR = 6 then RS = 3 since 9 - 6 = 3.
