Answer 1

To determine which vehicles are safely obeying the speed limit of 55 mph, we need to calculate the speed of each vehicle using the formula:

\[
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
\]

Let's calculate the speed for each vehicle:

1. **Ambulance:**
- Distance: 150 miles
- Time: 2 hours
\[
\text{Speed} = \frac{150 \text{ miles}}{2 \text{ hours}} = 75 \text{ mph}
\]

2. **Sports Car:**
- Distance: 216 miles
- Time: 4 hours
\[
\text{Speed} = \frac{216 \text{ miles}}{4 \text{ hours}} = 54 \text{ mph}
\]

3. **Train:**
- Distance: 182 miles
- Time: 2 hours
\[
\text{Speed} = \frac{182 \text{ miles}}{2 \text{ hours}} = 91 \text{ mph}
\]

4. **Limousine:**
- Distance: 318 miles
- Time: 6 hours
\[
\text{Speed} = \frac{318 \text{ miles}}{6 \text{ hours}} = 53 \text{ mph}
\]

5. **School Bus:**
- Distance: 162 miles
- Time: 3 hours
\[
\text{Speed} = \frac{162 \text{ miles}}{3 \text{ hours}} = 54 \text{ mph}
\]

Now we can check which vehicles are obeying the speed limit (55 mph):

- **Ambulance:** 75 mph (not obeying)
- **Sports Car:** 54 mph (obeying)
- **Train:** 91 mph (not obeying)
- **Limousine:** 53 mph (obeying)
- **School Bus:** 54 mph (obeying)

The vehicles that are safely obeying the speed limit of 55 mph are:

1. Sports Car
2. Limousine
3. School Bus

So the final answers are:
- A sports car travels 216 miles in 4 hours.
- A limousine travels 318 miles in 6 hours.
- A school bus travels 162 miles in 3 hours.
