Answer:
See below.
Step-by-step explanation:
Find the area of the rectangle using A = l*w = 26*20 = 520.
Now find the area of the semi circle using A = 1/2 πr². Since the instructions do not say the diameter of the semi circle assume it is 20 or 26.
If it is 20: r = 10 and the area is A = 1/2 π10²=50π = 157.
If it is 26: r = 13 and the area is A = 1/2π13² = (84.5)π = 265.33.
The area of the paperboard that remains will be the area of the rectangle minus the area of the semi circle.
If the diameter of the semi circle is 20 then 520 - 157 = 363.
If the diameter of the semi circle is 26 then 520 - 254.67.

Let n be the speed of Fritzs' car, and n+6 be the speed of the train. Then:
4/5 (n)=2/3 (n+6)
4n/5=2n+12/3
10n+60=12n
2n=60
n=30
Fritz travels 4/5(30), or 24 miles to work
