She drove 2 hours at 70 miles per hour, so she drove 70 * 2 = 140 miles total.
The jet traveled 400 miles per hour for 2 hours for a total of 400 * 2 = 800 miles.
Total miles = 140 + 800 = 940 miles.
The answer is C.

Answer:
65° and 115°
Step-by-step explanation:
let one angle be x then the other is x + 50
The sum of 2 supplementary angles = 180°, hence
x + x + 50 = 180
2x + 50 = 180 ( subtract 50 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65
Thus the 2 angles are x = 65° and x + 50 = 65 + 50 = 115°
Answer:
Elimination is the best to solve it
Answer:
- field size: 1750 acres
- developed area: 1400 acres
Step-by-step explanation:
If the developed area is 80% of the field, and the undeveloped area is 20%, then the developed area is 4 times the undeveloped area, so is ...
developed area = 4 × 350 acres
developed area = 1400 acres
Then the total area is ...
total area = developed area + undeveloped area = (1400 +350) acres
total area = 1750 acres
