A crew will arrive in one week and begin filming a city for a movie the mayor is desparate to clean the city streets before film

Nonamiya [84]

Answer:

a.323.03hrs,

b.No. Time not enough

Step-by-step explanation:

One team takes $\frac{1}{600}$ of the job per hour,

Team two takes $\frac{1}{700}$ of the job together.

#to get what times it takes the two to clean together, we find the LCM of their work rates:

$LCM=\frac{1}{600}+\frac{1}{700}\\=\frac{13}{4200}\\$ #It takes the two13/4200 of the job per hour.

Combined work rate is thus $4200\div 13=323.08hrs$

Hence it takes the two teams 323.03hrs to clean the streets working together.

b.The crew team is set to begin in 1 week(7days). We therefore convert our time into days/weeks to verify viability;

Since one day equals 24hrs, the team will take

$323.03/24=13.46days$

13.46days>7days

#NO, The time is not enough since 13.46days is higher than the 1week(7day) timeline.
