I'm guessing that the word 'and' refers to addition, so
twice a quarter = 2 * (1/4) = 2/4 = 1/2
quarter doubled is the same = 1/2
so 1/2 + 1/2 = 1 (the first part of the question)
2nd part:
half a half = (1/2) * (1/2) = 1/4
half halved = (1/2)/2 = 1/4
so 1/4 + 1/4 = 1/2
so the first part 'twice a quarter and a quarter doubled'is greater, because 1 > (1/2)
One half is greater than one quarter.
17 doubled once is 34doubled again is 68.so 17 doubled twice is 68.
Since the number is halved when reduced by 13, then the number must be twice 13 = 26.

Then it takes twice as much time, or half as much time, respectively, to cover it, provided that the speed never changes.
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
One half is greater than one quarter.
17 doubled once is 34doubled again is 68.so 17 doubled twice is 68.
2/4 is twice as much as 1/4
Since the number is halved when reduced by 13, then the number must be twice 13 = 26.
