Two business partners who operate a truck have agreed that neither partner will drive the truck for more than 10 hours in any calendar day. The graph shows the number of kilometers that the truck was driven during each of 12 consecutive calendar days. On days 7, 8, 9, and 11, the driving time was equally divided between the two partners. On each of the other days, only one of the partners drove. No one else drove the truck. Everywhere the truck was driven during the period shown, the maximum speed limit was 100 kilometers per hour or less.
Based on the information provided, select from each drop-down menu the option that creates the most accurate statement.
| Text Component | Literal Content | Simple Interpretation |
|---|---|---|
| Business partners | Two business partners who operate a truck | Two people own and drive one truck |
| Driving time rule | Neither partner will drive the truck for more than 10 hours in any calendar day | Each partner must not drive more than 10 hours per day |
| Time period | 12 consecutive calendar days | Data is for 12 continuous days |
| Shared driving days | Days 7, 8, 9, and 11: driving time equally divided between two partners | On those days, both partners drove equal times |
| Other days | On each of the other days, only one partner drove | Days 1-6, 10, and 12: only one partner drove |
| Exclusivity | No one else drove the truck | Only the two named partners ever drove |
| Speed limit | Maximum speed limit was 100 km/h or less everywhere the truck was driven | Truck could be driven at most 100 km/h |
| Chart Feature | What is Shown | What This Tells Us |
|---|---|---|
| Y-axis | Kilometers driven: 0 to 1,600 in 200 km increments | Daily distances up to 1,600 km are possible |
| X-axis | 12 consecutive days | Each day labeled 1-12 |
| Highest values | Days 7 (~1450 km), 8 (~1400 km) | Maximum distances occur on shared-driving days |
| Other high values | Days 6 (~1240 km), 10 (~1220 km), 11 (~1240 km) | Several days above 1,000 km, including some single-driver |
| Days below 1,000 km | Days 1-5, 9, and 12 | On these, 10 hr at 100 km/h could cover the distance |
| Pattern | Peaks and plateaus, especially days 6-8 and 10-11 | Intense activity in that range of days |
If the information in the graph and accompanying text is accurate and if neither driver violated the speed limit at any time, it follows that the agreed-on maximum driving time per day was exceeded on Day [BLANK 1]
and also on Day [BLANK 2]
When drivers did not break the speed limit of 100 km/hr and the maximum agreed driving time is 10 hours per day, any day where a single driver covered more than 1,000 km means the agreement was violated. On Day 6, a single driver covered 1,240 km; on Day 10, a single driver covered 1,220 km. These are the only days among the choices where the agreement was certainly exceeded.
Both blanks are independent. Each asks you to find a separate day where the maximum driving time was exceeded, using the same reasoning but not relying on each other. Solving one blank does not provide information about the other.
