Answer: Option D

Explanation:

Let's track the bus's movements step by step:

The bus travels 2 blocks north.
Then, it travels 2 blocks east.
Next, it goes 1 block south.
Afterward, it continues 2 blocks east.
Finally, it moves 1 block south.

Now, let's see where the bus is in relation to the hotel:

It went 2 blocks north initially but then moved 1 block south, so it's still 1 block north of the starting point.
It went 2 blocks east and then 2 blocks east again, which adds up to 4 blocks east of the starting point.

So, the bus is 1 block north and 4 blocks east of the hotel. Therefore, the answer is 4 blocks east.

View Answer	Favorite Question

Answer: Option A

Explanation:

Let the batter's career average before her 17th inning be "x" runs per inning.

After her 17th inning, her career average increased by 3 runs, so her new average is (x + 3) runs per inning.

In the first 16 innings, she scored a total of 16x runs.

After her 17th inning, her total runs scored became 16x + 87 runs.

Now, we can set up an equation:

(16x + 87) / 17 = (x + 3)

Now, solve for x:

16x + 87 = 17x + 51

87 - 51 = 17x - 16x

36 = x

So, her career average before the 17th inning was 36 runs per inning, and her new average after the 17th inning is (36 + 3) = 39 runs per inning.

View Answer	Favorite Question

Answer: Option C

Explanation:

A + B can do the work in 12 days.

In a single day A + B will do 1/12 th portion of the work.

B + C can do the work in 15 days.

In a single day B + C will do 1/15 th portion of the work.

A + C can do the work in 20 days.

In a single day A + C will do 1/20 th portion of the work.

In a day (A + B) + (A + C) + (C + A) will do = (1/12) + (1/15) + (1/20) portion of the work.

2(A + B + C) = (1/12) + (1/15) + (1/20) = 1/5 portion of the work.

Then, (A + B + C) will do = 1/10 portion of the work in a day

A + B + C will complete the work in 10 days.
