On a certain number line, there are 10 marks evenly spaced. If the fifth mark has a value equal to 2.3 and the tenth mark's value is equal to 3.8, then what is the value of the second mark?  Select:
A) 0.3
B) 1.1
C) 1.4
D) 1.5
E) 1.7
5th Mark = 2.3   10th Mark = 3.8   Evenly spaced means we have 5 gaps of equal length between 5th and 10th mark.   So, Each gap distance = 3.8 - 2.3 /10 = 0.3   So, 2nd mark will be  2.3 - 3*0.3=
