Question

the highway has a maximum speed limit of 55 mph. which vehicles are safely obeying this speed limit? check all that apply. a limousine travels 318 miles in 6 hours. a sports car travels 216 miles in 4 hours. an ambulance travels 150 miles in 2 hours. a school bus travels 162 miles in 3 hours. a train travels 182 miles in 2 hours.

Explanation:

To determine which vehicles are safely obeying the 55 mph speed limit, we calculate the speed of each vehicle using the formula \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \).

Step 1: Calculate the speed of the limousine

The limousine travels 318 miles in 6 hours. Using the speed formula:
\( \text{Speed} = \frac{318}{6} = 53 \) mph. Since \( 53 \leq 55 \), the limousine is within the speed limit.

Step 2: Calculate the speed of the sports car

The sports car travels 216 miles in 4 hours. Using the speed formula:
\( \text{Speed} = \frac{216}{4} = 54 \) mph. Since \( 54 \leq 55 \), the sports car is within the speed limit.

Step 3: Calculate the speed of the ambulance

The ambulance travels 150 miles in 2 hours. Using the speed formula:
\( \text{Speed} = \frac{150}{2} = 75 \) mph. Since \( 75 > 55 \), the ambulance is not within the speed limit.

Step 4: Calculate the speed of the school bus

The school bus travels 162 miles in 3 hours. Using the speed formula:
\( \text{Speed} = \frac{162}{3} = 54 \) mph. Since \( 54 \leq 55 \), the school bus is within the speed limit.

Step 5: Calculate the speed of the train

The train travels 182 miles in 2 hours. Using the speed formula:
\( \text{Speed} = \frac{182}{2} = 91 \) mph. Since \( 91 > 55 \), the train is not within the speed limit.

Answer:

A. A limousine travels 318 miles in 6 hours.
B. A sports car travels 216 miles in 4 hours.
D. A school bus travels 162 miles in 3 hours.
