## anonymous one year ago Alanna can detail a car in 45 minutes. Robbie can detail a car in 30 minutes. If they work together, how many minutes does it take them to detail a car?

1. anonymous

want the quick snappo method?

2. anonymous

15 minutes 18 minutes 75 minutes 90 minutes

3. anonymous

Yes!!

4. anonymous

ok oh and i see you have answer choices, obvious the last two are rather silly because working together is evidently quicker than working alone

5. anonymous

snap method $\frac{30\times 45}{30+45}$ compute that easy right?

6. anonymous

seems easy enough

7. anonymous

1350/ 75

8. anonymous

18?

9. anonymous

it is notice i only used the numbers given a detailed explanation if you like, but that always works in this problem yes, 18

10. anonymous

No, I'm good:)

11. anonymous

lol fine

12. anonymous

Will you help with another?

13. anonymous

if i can sure

14. anonymous

wow i am sure i can come up with some answer but this question goes right in to the "bad math" pile maybe she scatters the leaves in one second!

15. anonymous

lollll :D

16. anonymous

i mean for real maybe she just comes along with a leave blower and blows them all to hell where does this question come from ?

17. anonymous

Summer math packet :)))

18. anonymous

heck i will make a guess that they want you to solve $\frac{1}{15}+\frac{1}{x}=\frac{1}{20}$ which gives $$x=-60$$ go with 60 and tell your teacher that satellite says they should be ashamed

19. anonymous

hahaha!!!! I'll tell him/her when I meet them next year hahah a

20. anonymous

in truth i have no idea what they want you to solve, so i would not bet more than \$1.25 on my answer

21. anonymous

No biggie :) I trust you
