In Saturday's 8 mile race Sarah's goal was to complete 1/2 of the run in 48 minutes. After that time had elapsed Sarah had run 2/3 of the total race. Which shoes how far ahead of Pace Sarah is?

A.1/6
B.3/6
C.7/8
D.2/6
A?

Before Chad shared his starburst with his friends he had 12 pieces. He gave 2 orange ones to Katy and 2 green ones and a red one to BRett. Which expression can be used to find the number of starbursts that Chad had left?
A.12-(2/12+3/12)
B.1-(1/6+1/4)
C.1/6+1/4
D.2/12+3/12
A?

Your first answer is right.

But the second problem has a similar flaw to the one we discussed a few minutes ago.

The problem ask us to find the number of starbursts Chad had left.

12 - (2 + 3) = 7 pieces left

None of your answer choices is correct.

12 - (2/12 + 3/12) = 12 - 5/12 = 11 7/12

So should I ask the teacher about the two problems that are faulty? But is A for the starburst question partly right? Is it just missing a few stuff like in the other question?

Yes, ask your teacher. None of the answers comes even close to answering the question.

To answer the first question, we need to determine how far Sarah has run at the 48-minute mark. We are told that Sarah's goal was to complete 1/2 of the run in 48 minutes. This means that if she achieves her goal, she will have run 1/2 of the total distance of the race.

Therefore, we can set up the equation: 2/3 * Total distance = 1/2 * Total distance

To find the answer, we can solve for the Total distance:
2/3 * Total distance = 1/2 * Total distance
2/3 = 1/2
Since the fractions are not equal, we can conclude that Sarah is ahead of pace.

To determine how far ahead of pace Sarah is, we can subtract the amount of distance she has actually run from the total distance to get the remaining distance.

The equation becomes: Total distance - 2/3 * Total distance = Remaining distance
Simplifying the equation gives: 1/3 * Total distance = Remaining distance

To find the answer, we need to compare the remaining distance to the total distance. We want to express it as a fraction relative to the total distance.

Now, since Sarah has completed 2/3 of the total distance, the remaining distance is equal to 1/3 of the total distance.

Comparing the remaining distance to the total distance gives us: Remaining distance / Total distance = 1/3 / 1 = 1/3

Therefore, Sarah is ahead of pace by 1/3 of the total distance.

Answer: D. 2/6

Now let's move on to the second question.

To find the number of starbursts Chad has left, we need to subtract the starbursts he gave away from the total number he initially had.

According to the question, Chad initially had 12 starbursts. He gave 2 orange ones to Katy and 2 green ones and a red one to Brett.

So the number of starbursts he gave away is 2 + 2 + 1 = 5.

The expression that represents the number of starbursts Chad has left is: Total number initially - number given away = Number left
12 - 5 = 7

Therefore, Chad has 7 starbursts left.

Answer: C. 1/6 + 1/4
