If Cassie works at a constant rate, will Cassie have enough time to

Hello Mate,

As per your statement (1), Casey isn't working at a constant speed. The question asks if she works at a constant speed, will she be able to bake the pies? The rate here is 1/3(T) for a pie. Since she has 4 pies she won't be able to complete the job in 'T' units. The answer is 'NO'. Hence A is sufficient.

Cheers!

We need to determine whether Cassie has enough time to bake 4 pies.

Statement One Alone:

If Cassie had one-third as much time, she would be able to bake one pie.

We can create a proportion in which t = the total amount of time Cassie has to bake 4 pies and x = the number of pies she can bake in time t:

(1/3)t/1 = t/x

t/3 = t/x

tx/3 = t

tx = 3t

x = 3

Since Cassie can only bake 3 pies in the allotted time, she does not have enough time to bake 4 pies. Statement one alone is sufficient to answer the question. We can eliminate answer choices B, C, and E.

Statement Two Alone:

Cassie can fit three pies in her oven at one time.

Knowing the number of pies that Cassie can fit in her oven does not help us answer the question.

Answer: A

suppose she takes 2 min to bake a cake. it means she needs 8 mins. She has 9 mins to bake those cake. then 1/3rd time would be 3 min which is enough to bake a single cake.
if she has 6 min then 1/3rd is 2 min which is also enough for a single cake. so how can A be the answer :/

S1 - 1/3 time to bake 1 pie which essentially points to baking 3 cakes in the allotted time. So a sufficient No.

S2 - 3 cakes at time means she can bake the 4th cake in the second round, or there won't be enough time to make the cake. So insufficient.

IMO, Answer is A.

I must say wonderful ...

'one-third as much time" what does it mean ? 1/3 more

Let me ask you: how does say "TWICE as much time" translates? Int's it 2*t? So, "one-third as much time" means 1/3*t.
