Answer 1

To determine which vehicles are safely obeying the speed limit of 55 mph, we need to calculate the speed of each vehicle by dividing the distance traveled by the time taken. The formula for speed is:

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

Now, let's calculate the speed of each vehicle:

1. Train:

   • Distance: 182 miles
   • Time: 2 hours
   • Speed = \( \frac{182 \text{ miles}}{2 \text{ hours}} = 91 \text{ mph} \)

2. Ambulance:

   • Distance: 150 miles
   • Time: 2 hours
   • Speed = \( \frac{150 \text{ miles}}{2 \text{ hours}} = 75 \text{ mph} \)

3. Sports Car:

   • Distance: 216 miles
   • Time: 4 hours
   • Speed = \( \frac{216 \text{ miles}}{4 \text{ hours}} = 54 \text{ mph} \)

4. Limousine:

   • Distance: 318 miles
   • Time: 6 hours
   • Speed = \( \frac{318 \text{ miles}}{6 \text{ hours}} = 53 \text{ mph} \)

5. School Bus:

   • Distance: 162 miles
   • Time: 3 hours
   • Speed = \( \frac{162 \text{ miles}}{3 \text{ hours}} = 54 \text{ mph} \)

Now, let’s summarize the speeds:

• Train: 91 mph (exceeds limit)
• Ambulance: 75 mph (exceeds limit)
• Sports Car: 54 mph (within limit)
• Limousine: 53 mph (within limit)
• School Bus: 54 mph (within limit)

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

1. Sports Car (54 mph)
2. Limousine (53 mph)
3. School Bus (54 mph)

The three vehicles that are safely obeying the speed limit are the Sports Car, Limousine, and School Bus.
