Question

A bus travels 40 miles per hour for 2 hours. How far does it travel?

• A. 70 miles
• B. 80 miles
• C. 90 miles
• D. 100 miles

Hint:

Think of "miles per hour" as a rate. If the bus travels 40 miles in one hour, it will travel twice that distance in two hours. This intuitive approach can often solve these problems without formally writing the formula.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This problem requires the calculation of distance traveled, given a constant speed and a specific duration of time.
Step 2: Key Formula or Approach:
The relationship between distance, speed, and time is given by the formula:
Distance = Speed \(\times\) Time
Step 3: Detailed Explanation:
The given information is:
- Speed = 40 miles per hour
- Time = 2 hours
The units are consistent, so we can directly apply the formula:
\[ \text{Distance} = 40 \frac{\text{miles}}{\text{hour}} \times 2 \text{ hours} \] \[ \text{Distance} = 80 \text{ miles} \] Step 4: Final Answer:
The bus travels 80 miles. This corresponds to option (B).
