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? 12.2 × 1.45 610 4880 +_(___)_ Brian biked a distance of miles.

17.69 miles

Step-by-step explanation:

Activity time (hours) :

Activity - - - - - - - - - - - - - time (hours)

Hiking - - - - - - - - - - - - - - - - - - - - 3

Mountain biking - - - - - - - - - - - 1.45

Horseback riding - - - - - - - - - - 1.2

Cross-country skiing - - - - - - - - 0.75

Average speed = 12.2 miles per hour.

How many miles did Brian bike?

Recall;

Speed = distance ÷ time

Distance = speed × time

Speed = 12.2 mi/hr

biking time = 1.45 hours

Distance (mountain biking) = 12.2 × 1.45 = 17.69 miles

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
