Tweety cannot fly

Tweety is not a bird

All birds can fly

If some birds can fly and Tweety is a bird, it's possible that Tweety can fly, but it doesn't guarantee that all birds can fly. The correct conclusion is that Tweety can fly based on the given information.

5. A bus leaves the station at 8:00 AM and travels at an average speed of 60 mph. Another bus leaves the same station at 10:00 AM and travels at an average speed of 75 mph. At what time will the second bus catch up with the first bus?

12:00 PM

6:00 PM

2:00 PM

3:00 PM

1. Calculate the head start:

The first bus has a 2-hour head start (10:00 AM - 8:00 AM = 2 hours).

2. Calculate the relative speed:

The second bus is 15 mph faster than the first bus (75 mph - 60 mph = 15 mph).

3. Calculate the time to catch up:

To catch up, the second bus needs to cover the distance the first bus traveled in its 2-hour head start.

Distance covered by the first bus in 2 hours: 60 mph * 2 hours = 120 miles

Time for the second bus to cover 120 miles at a relative speed of 15 mph: 120 miles / 15 mph = 8 hours

4. Calculate the time the second bus catches up:

The second bus leaves at 10:00 AM and takes 8 hours to catch up, so it will catch up at 10:00 AM + 8 hours = 6:00 PM.

Explanation

1. Calculate the head start:

The first bus has a 2-hour head start (10:00 AM - 8:00 AM = 2 hours).

2. Calculate the relative speed:

The second bus is 15 mph faster than the first bus (75 mph - 60 mph = 15 mph).

3. Calculate the time to catch up:

To catch up, the second bus needs to cover the distance the first bus traveled in its 2-hour head start.

Distance covered by the first bus in 2 hours: 60 mph * 2 hours = 120 miles

Time for the second bus to cover 120 miles at a relative speed of 15 mph: 120 miles / 15 mph = 8 hours

4. Calculate the time the second bus catches up:

The second bus leaves at 10:00 AM and takes 8 hours to catch up, so it will catch up at 10:00 AM + 8 hours = 6:00 PM.

6. What is the next letter in the sequence? W I T N L _ I T

N

W

S

I don't know

The sequence is based on the first letters of the words in the question itself:

Therefore, the next letter is W.

The sequence goes like this -

W I T N L W I T

Explanation

The sequence is based on the first letters of the words in the question itself:

Therefore, the next letter is W.

The sequence goes like this -

W I T N L W I T

7. A googol is a 1 followed by a hundred zeroes.What is half of a googol?

1 followed by fifty zeroes

5 followed by fifty zeroes

9 followed by 99 zeroes

5 followed by 99 zeroes

It makes sense...
for example, half of a hundred, which is one followed by two zeroes, is not ten, which is one followed by one zero.

Explanation

It makes sense...
for example, half of a hundred, which is one followed by two zeroes, is not ten, which is one followed by one zero.

9. I have a standard 8x8 chessboard. I remove a square, and tile the rest without any overlap with 1x3 dominoes. How many squares could have been the one I removed at the start?

It's not possible

2

4

Any of them

Probably the hardest question; 99.99% of people guessed. This is because you can't tile a 8x8 chessboard with a square removed unless that square is either c3, f3, c6 or f6. And if you disagree, try to find another square that works and DRAW the diagram (not just in your head) - then you will see where you went wrong.

10. If it takes five fence posts to mark out five meters, how many does it take to mark out ten meters?

9

10

11

Can't work it out.

Assuming the fence posts are evenly spaced, 5 posts over 5 meters means they are 1 meter apart. To cover 10 meters, you'll need a post at the start (0 meters) and another every meter after that. This pattern continues until you reach 10 meters, requiring a final post at the end. Therefore, you need 11 posts in total.
