Answer:
50 hours
Step-by-step explanation:
Josh = 50 hours
frank worked 50 hours less and twice as many hours as josh did.
Frank = 2(Josh) - 50 hours

Answer: D) Absolute Value
Step-by-step explanation:
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.)
