The highway has a maximum speed limit of 55 mph. Which vehicles are safely obeying this speed limit? Check the three that apply. (3 points)

Question

An ambulance travels 150 miles in 2 hours.
A train travels 182 miles in 2 hours.
A limousine travels 318 miles in 6 hours.
• A sports car travels 216 miles in 4 hours.
• A school bus travels 162 miles in 3 hours.

Answer 1

To determine which vehicles are safely obeying the 55 mph speed limit, 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: \[ \text{Speed} = \frac{150 \text{ miles}}{2 \text{ hours}} = 75 \text{ mph} \]

2. Train: \[ \text{Speed} = \frac{182 \text{ miles}}{2 \text{ hours}} = 91 \text{ mph} \]

3. Limousine: \[ \text{Speed} = \frac{318 \text{ miles}}{6 \text{ hours}} = 53 \text{ mph} \]

4. Sports Car: \[ \text{Speed} = \frac{216 \text{ miles}}{4 \text{ hours}} = 54 \text{ mph} \]

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

Now, let's compare each calculated speed to the 55 mph speed limit:

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

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

• Limousine (53 mph)
• Sports Car (54 mph)
• School Bus (54 mph)

So, the three vehicles that are safely obeying the speed limit are the limousine, sports car, and school bus.
