How far did Brian hike?
A. 1.086 miles
B. 10.86 miles
C. 100.86 miles
D. 108.6 miles
Answer (1)
The problem provides Brian's average hiking speed and hiking time.
We use the formula distance = speed × time.
Substituting the given values, we calculate the distance: 3.62 × 3 = 10.86 .
Therefore, Brian hiked 10.86 miles.
Explanation
Understanding the Problem We are given Brian's average hiking speed and the time he spent hiking. We need to find the distance he hiked.
Stating the Formula We can use the formula: distance = speed × time.
Calculating the Distance We are given that Brian's average hiking speed is 3.62 miles per hour and he hiked for 3 hours. Substituting these values into the formula, we get:
distance = 3.62 miles/hour × 3 hours
distance = 10.86 miles
Final Answer Therefore, Brian hiked 10.86 miles.
Examples
Understanding how to calculate distance based on speed and time is useful in many real-life situations. For example, if you are planning a road trip, you can use your average speed and the time you expect to drive to estimate the distance you will cover. Similarly, runners and cyclists use this calculation to track their progress and plan their training routes. This simple formula helps in everyday planning and estimation.
