Answer:
Where is M??
Step-by-step explanation:
Answer:
them some expensive pencils
For this case what we can do is the following rule of three:
2/3 of a box ------> 1/2 minutes
x of a box ---------> 1 minute
Clearing x we have:
x = (1 / (1/2)) * (2/3)
Rewriting:
x = 2 * (2/3)
x = 4/3
Answer:
the number of boxes per minute that the machine packs is:
x = 4/3
Answer:
No, They will do it in more than an hour
t=1,1 h
Step-by-step explanation:
Vh=1mile/12min, Vt=1mile/15min They will meet to same time th=tt
sh=x, st=10-x, so V=s/t we have Vh=sh/t ; Vt=st/t ; t=(sh/Vh) = (st/Vt);
; so
: if Vh=sh/t then 
Note: V=s/t : but in this case are 12 min (t) per mile (s), so
