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.
