Brian visited a mountain park with trails for hiking, mountain biking, horseback riding, and cross-country skiing. The chart shows the time Brian spent doing each activity.

A 2-column table with 4 rows titled Brian's Activity time (hours). Column 1 has entries hiking, mountain biking, horseback riding, cross-country skiing. Column 2 has entries 3, 1.45, 1.2, 0.75.

Brian biked the yellow trail loop that circles the park. He rode at an average speed of 12.2 miles per hour. How many miles did Brian bike?

1 answer

To find the distance Brian biked, we use the formula:

\[ \text{Distance} = \text{Speed} \times \text{Time} \]

In this case, Brian's average speed is 12.2 miles per hour and the time he spent mountain biking is 1.45 hours.

Now, we can calculate the distance:

\[ \text{Distance} = 12.2 , \text{miles/hour} \times 1.45 , \text{hours} \]

Let's perform the multiplication:

  1. \( 12.2 \times 1.45 \):
    • First, multiply 12.2 by 1.45:
    • \( 12.2 \times 1.45 = 17.69 \)

So, Brian biked a distance of 17.69 miles.

Therefore, the answer is:

Brian biked a distance of 17.69 miles.
