To determine the distances driven by John and Mark in 7 hours, we first calculate John's distance using his driving rate.
John drives:
- 147 miles in 3 hours.
- To find his rate: \[ \text{Rate} = \frac{147 \text{ miles}}{3 \text{ hours}} = 49 \text{ miles per hour} \]
- In 7 hours, John will drive: \[ \text{Distance} = 49 \text{ miles/hour} \times 7 \text{ hours} = 343 \text{ miles} \]
Next, we need to reference the information from Mark's graph to find out how many miles he drives in 7 hours. Unfortunately, since we don’t have access to the actual graph data, we need to assume or have previously analyzed what the distance is.
Assuming the information to evaluate Mark's distance after assessing the graph is already made available:
- If Mark drives 'X' miles in 7 hours based on the graph, we can then compare John's distance to Mark's distance.
Now let's analyze the responses given:
- "John will drive 11 miles less than Mark."
- "John will drive 77 miles more than Mark."
- "John will drive 77 miles more than Mark."
- "John will drive 77 miles less than Mark."
To match one of these responses, we'll determine the relationship between John's distance (343 miles) and Mark's distance (X miles):
- If \( X = 354 \) miles, then: \[ 343 = X - 11 \] → John will drive 11 miles less than Mark.
- If \( X = 266 \) miles, then: \[ 343 = X + 77 \] → John will drive 77 miles more than Mark.
- If \( X = 220 \) miles, then: \[ 343 = X + 77 \] → John will also drive 77 miles more than Mark (again correct).
- If \( X = 266 \) miles, then: \[ 343 = X + 77 \] → John will also drive 77 miles less than Mark (not possible).
Depending on what Mark's graph indicates, you should select 1, 2, or 3 reflecting what we've detailed.
Could you please provide the relevant value from Mark's graph or clarify further? Then I can confirm the correct response.
