Answer:
3. about 7.48 hours
4. about 1.8892 hours
Step-by-step explanation:
Both of these questions make use of the relation ...
time = distance / speed
3. time = (965 mi)/(129 mi/h) ≈ 7.48062 h ≈ 7.48 h
__
4. time = (612.1 mi)/(324 mi/h) ≈ 1.889198 h ≈ 1.8892 h
(We have rounded the time to sufficient precision so that the distance at the given speed rounds to the number given.)
The answer is B because if the result is 3/4 and the question is asking to the result then you would an equation.

Answer:
21 ft
Step-by-step explanation:
C = 2πr
Filling in the given values, we have ...
131.88 ft = 2·3.14·r . . . . we can find r by dividing by its coefficient
131.88 ft/6.28 = r = 21 ft
