A train travels 182 miles in 2 hours. A limousine travels 318 miles in 6 hours. A limousine travels 318 miles in 6 hours. A school bus travels 162 miles in 3 hours.

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.
