Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles

Area of the sector is 4.71 sq units
Step-by-step explanation:
- Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.
Area of the sector = πr²(C/360) = 9π × 60/360
= 9 × 3.14 × 1/6
= 28.26/6 = 4.71 sq units
