Step-by-step explanation:
The time William would arrive in town B IS 1 : 47 pm.
<h3>What time will William arrive in town B?</h3>
The first step is to determine the distance and the time of Dennis's travel.
Time = 14 hours (2 pm + 12) - 10 hours = 4 hours
Distance = time x average speed
4 x 52 = 208 miles
The second step is to determine the time of William's travel:
Distance / average speed = time
208 / 40 = 5.20 = 5 hours 12 minutes
Time William left for the trip = 10 am - 1 hour 25 minutes = 8 :35am
Time he would reach town B = 8 : 35am + 5 hours 12 minutes = 13 hours 47 minutes = 1 : 47 pm

Answer:
Step-by-step explanation:
I'll show you how to do the first one; the other are exactly the same, so pay attention.
The formula for arc length is
where θ is the central angle's measure. It just so happens that the measure of the central angle is the same as the measure of the arc it intercepts. Our arc shows a measure of 40°; this measure is NOT the same as the length. Measures are in degrees while length is in inches, or cm, or meters, etc. Going off that info, our central angle measures 40°. Filling in the formula and using 3.1415 for π:
. I'm going to reduce that fraction a bit (and I'll use the same reduction in the Area of a sector coming up next):
which makes
AL = 2.09 units. Now for Area of the Sector. The formula is almost identical, but instead uses the idea that the area of a circle is πr²:
where θ is, again, the measure of the central angle (which is the same as the measure of the arc it intercepts). Filling in:
which simplifies a bit to
. As you can see, the 9's cancel each other out, leaving you with
units²
