Jacksonville Fl and Tallahassee FL will be about 125 miles apart in real life.
Answer:
I do not know but trying to help I think it is D
Step-by-step explanation:
Okay, so the rate is 1 job / hours, so:
1/3 + 1/7 (This covers both their work rates) = 1/n (n represents the time it take for them to work together)
Get the LCD:
7/21+ 3/21 = 1/n
10/21 = 1/n
Cross multiply:
10n = 21
n = 2.1
It will take them 2.1 hours, or 2 hours and 6 minutes
It would be 8 because 3 less than 8.
Hope this helps! :D
