Nancy took a 3 hour drive. She went 45 miles before she got caught in a storm. Then she drove 60 miles at 8 mph less than she had driven when the weather was good. What was her speed, in miles per hour, driving in the storm?

where is the figure

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
